These errors are non-harmful and should be transient. They either
imply:
- compilation database returned stale results for TUs and it'll be fixed once
  it's updated to match project state.
- a TUs dependencies has changed and some headers no longer exist. this should
  be fixed with the next indexing cycle.

In either case the user will have some stale symbols in their index until clangd
restarts and the underlying issue is resolved. On the downside these logs are
confusing users when there's another issue.

[RISCV] Enable CGP to sink splat operands of VP intrinsics

This patch brings better splat-matching to our VP support, by sinking
splat operands of VP intrinsics back into the same block as the VP
operation. The list of VP intrinsics we are interested in matches that
of the regular instructions.

Some optimization is still lacking. For instance, our VL nodes aren't
recognized as commutative, so splats must be on the RHS. Because of
this, we limit our sinking of splats to just the RHS operand for now.
Improvement in this regard can come in another patch.

D111986 added the generic `__builtin_elementwise_abs()` intrinsic with the same integer absolute behaviour as the SSE/AVX instructions (abs(INT_MIN) == INT_MIN)

This patch removes the `__builtin_ia32_pabs*` intrinsics and just uses `__builtin_elementwise_abs` - the existing tests see no changes:
```
__m256i test_mm256_abs_epi8(__m256i a) {
  // CHECK-LABEL: test_mm256_abs_epi8
  // CHECK: [[ABS:%.*]] = call <32 x i8> @llvm.abs.v32i8(<32 x i8> %{{.*}}, i1 false)
  return _mm256_abs_epi8(a);
}
```
This requires us to add a `__v64qs` explicitly signed char vector type (we already have `__v16qs` and `__v32qs`).

[clang][deps] Ensure filesystem cache consistency

The minimizing filesystem used by the dependency scanner isn't great when it comes to the consistency of its caches. There are two problems that can be exposed by a filesystem that changes during dependency scan:
1. In-memory cache entries for original and minimized files are distinct, populated at different times using separate stat/open syscalls. This means that when a file is read with minimization disabled, its contents might be inconsistent when the same file is read with minimization enabled at later point (and vice versa).
2. In-memory cache entries are indexed by filename. This is problematic for symlinks, where the contents of the symlink might be inconsistent with contents of the original file (for the same reason as in problem 1).

This patch ensures consistency by always stating/reading a file exactly once. The original contents are always cached and minimized contents are derived from that on demand. The cache entries are now indexed by their `UniqueID` ensuring consistency for symlinks too. Moreover, the stat/read syscalls are now issued outside of critical section.

Depends on D115935.

[clang][deps] Handle symlinks in minimizing FS

The minimizing and caching filesystem used by the dependency scanner can be configured to **not** minimize some files. That's necessary when scanning a TU with prebuilt inputs (i.e. PCH) that refer to the original (non-minimized) files. Minimizing such files in the dependency scanner would cause discrepancy between the current perceived state of the filesystem and the file sizes stored in the AST file. By not minimizing such files, we avoid creating the discrepancy.

The problem with the current approach is that files that should not be minimized are identified by their path. This breaks down when the prebuilt input (PCH) and the current TU refer to the same file via different paths (i.e. symlinks). This patch switches from paths to `llvm::sys::fs::UniqueID` when identifying ignored files. This is consistent with how the rest of Clang treats files.

Depends on D114966.

[X86] Remove `__builtin_ia32_pmax/min` intrinsics and use generic `__builtin_elementwise_max/min`

D111985 added the generic `__builtin_elementwise_max` and `__builtin_elementwise_min` intrinsics with the same integer behaviour as the SSE/AVX instructions

This patch removes the `__builtin_ia32_pmax/min` intrinsics and just uses `__builtin_elementwise_max/min` - the existing tests see no changes:
```
__m256i test_mm256_max_epu32(__m256i a, __m256i b) {
  // CHECK-LABEL: test_mm256_max_epu32
  // CHECK: call <8 x i32> @llvm.umax.v8i32(<8 x i32> %{{.*}}, <8 x i32> %{{.*}})
  return _mm256_max_epu32(a, b);
}
```
This requires us to add a `__v64qs` explicitly signed char vector type (we already have `__v16qs` and `__v32qs`).

[llvm] Cleanup header dependencies in ADT and Support

The cleanup was manual, but assisted by "include-what-you-use". It consists in

1. Removing unused forward declaration. No impact expected.
2. Removing unused headers in .cpp files. No impact expected.
3. Removing unused headers in .h files. This removes implicit dependencies and
   is generally considered a good thing, but this may break downstream builds.
   I've updated llvm, clang, lld, lldb and mlir deps, and included a list of the
   modification in the second part of the commit.
4. Replacing header inclusion by forward declaration. This has the same impact
   as 3.

Notable changes:

- llvm/Support/TargetParser.h no longer includes llvm/Support/AArch64TargetParser.h nor llvm/Support/ARMTargetParser.h
- llvm/Support/TypeSize.h no longer includes llvm/Support/WithColor.h
- llvm/Support/YAMLTraits.h no longer includes llvm/Support/Regex.h
- llvm/ADT/SmallVector.h no longer includes llvm/Support/MemAlloc.h nor llvm/Support/ErrorHandling.h

You may need to add some of these headers in your compilation units, if needs be.

As an hint to the impact of the cleanup, running

clang++ -E  -Iinclude -I../llvm/include ../llvm/lib/Support/*.cpp -std=c++14 -fno-rtti -fno-exceptions | wc -l

before: 8000919 lines
after:  7917500 lines

Reduced dependencies also helps incremental rebuilds and is more ccache
friendly, something not shown by the above metric :-)

[NFCI][Support] Avoid ASSERT_/EXPECT_TRUE(A <op> B)

The error messages in tests are far better when a test fails if the test
is written using ASSERT_/EXPECT_<operator>(A, B) rather than
ASSERT_/EXPECT_TRUE(A <operator> B).

This commit updates all of llvm/unittests/Support to use these macros
where possible.

This change has not been possible in:
- llvm/unittests/Support/FSUniqueIDTest.cpp - due to not overloading
  operators beyond ==, != and <.
- llvm/unittests/Support/BranchProbabilityTest.cpp - where the unchanged
  tests are of the operator overloads themselves.

There are other possibilities of this conversion not being valid, which
have not applied in these tests, as they do not use NULL (they use
nullptr), and they do not use const char* (they use std::string or
StringRef).

[llvm][ADT] Implement `BitVector::{pop_,}back`

LLVM Programmer’s Manual strongly discourages the use of `std::vector<bool>` and suggests `llvm::BitVector` as a possible replacement.

Currently, some users of `std::vector<bool>` cannot switch to `llvm::BitVector` because it doesn't implement the `pop_back()` and `back()` functions.

To enable easy transition of `std::vector<bool>` users, this patch implements `llvm::BitVector::pop_back()` and `llvm::BitVector::back()`.

Remove dependency from raw_ostream on <chrono>

The tryLockFor method from raw_fd_sotreamis the sole user of that
header, and it's not referenced in the mono repo. I still chose to keep
it (may be useful for downstream user) but added a transient type that's
forward declared to hold the duration parameter.

Notable changes:

- "llvm/Support/Duration.h" must be included in order to use tryLockFor.
- "llvm/Support/raw_ostream.h" no longer includes <chrono>

This sole change has an interesting impact on the number of processed
line, as measured by:

[InstCombine] Fold for masked gather when loading the same value each time.

This patch checks in the masked gather when the first operand value is a
splat and the mask is all one, because the masked gather is reloading the
same value each time. This patch replaces this pattern of masked gather by
a scalar load of the value and splats it in a vector.
