Support GCC [[gnu::attributes]] in C2x mode

GCC 10.1 introduced support for the [[]] style spelling of attributes in C
mode. Similar to how GCC supports __attribute__((foo)) as [[gnu::foo]] in
C++ mode, it now supports the same spelling in C mode as well. This patch
makes a change in Clang so that when you use the GCC attribute spelling,
the attribute is automatically available in all three spellings by default.
However, like Clang, GCC has some attributes it only recognizes in C++ mode
(specifically, abi_tag and init_priority), which this patch also honors.

[InstNamer] use 'i' for Instructions, not 'tmp'

As discussed in https://bugs.llvm.org/show_bug.cgi?id=45951 and
D80584, the name 'tmp' is almost always a bad choice, but we have
a legacy of regression tests with that name because it was baked
into utils/update_test_checks.py.

This change makes -instnamer more consistent (already using "arg"
and "bb", the common LLVM shorthand). And it avoids the conflict
in telling users of the FileCheck script to run "-instnamer" to
create a better regression test and having that cause a warn/fail
in update_test_checks.py.

Summary:
While clustering mem ops, AMDGPU target needs to consider number of clustered bytes
to decide on max number of mem ops that can be clustered. This patch adds support to pass
number of clustered bytes to target mem ops clustering logic.

[PGO] Improve the working set size heuristics under the partial sample PGO.

Summary:
The working set size heuristics (ProfileSummaryInfo::hasHugeWorkingSetSize)
under the partial sample PGO may not be accurate because the profile is partial
and the number of hot profile counters in the ProfileSummary may not reflect the
actual working set size of the program being compiled.

To improve this, the (approximated) ratio of the the number of profile counters
of the program being compiled to the number of profile counters in the partial
sample profile is computed (which is called the partial profile ratio) and the
working set size of the profile is scaled by this ratio to reflect the working
set size of the program being compiled and used for the working set size
heuristics.

The partial profile ratio is approximated based on the number of the basic
blocks in the program and the NumCounts field in the ProfileSummary and computed
through the thin LTO indexing. This means that there is the limitation that the
scaled working set size is available to the thin LTO post link passes only.

[Darwin] Add and adopt a way to query the Darwin kernel version

This applies the learnings from [1].  What I intended as a simple
cleanup made me realize that the compiler-rt version checks have two
separate issues:

1) In some places (e.g., mmap flag setting) what matters is the kernel
   version, not the OS version.
2) OS version checks are implemented by querying the kernel version.
   This is not necessarily correct inside the simulators if the
   simulator runtime isn't aligned with the host macOS.

This commit tackles 1) by adopting a separate query function for the
Darwin kernel version.  2) (and cleanups) will be dealt with in
follow-ups.

DAG: Fix getNode dropping flags if there's a glue output

The AMDGPU non-strict fdiv lowering needs to introduce an FP mode
switch in some cases, and has custom nodes to provide chain/glue for
the intermediate FP operations. We need to propagate nofpexcept here,
but getNode was dropping the flags.

Adding nofpexcept in the AMDGPU custom lowering is left to a future
patch.

Also fix a second case where flags were dropped, but in this case it
seems it just didn't handle this number of operands.

Test will be included in future AMDGPU patch.

[LiveDebugValues] Speed up removeEntryValue, NFC

Summary:
Instead of iterating over all VarLoc IDs in removeEntryValue(), just
iterate over the interval reserved for entry value VarLocs. This changes
the iteration order, hence the test update -- otherwise this is NFC.

This appears to give an ~8.5x wall time speed-up for LiveDebugValues when
compiling sqlite3.c 3.30.1 with a Release clang (on my machine):

```
          ---User Time---   --System Time--   --User+System--   ---Wall Time--- --- Name ---
  Before: 2.5402 ( 18.8%)   0.0050 (  0.4%)   2.5452 ( 17.3%)   2.5452 ( 17.3%) Live DEBUG_VALUE analysis
   After: 0.2364 (  2.1%)   0.0034 (  0.3%)   0.2399 (  2.0%)   0.2398 (  2.0%) Live DEBUG_VALUE analysis
```

The change in removeEntryValue() is the only one that appears to affect
wall time, but for consistency (and to resolve a pending TODO), I made
the analogous changes for iterating over SpillLocKind VarLocs.

[ELF] Refine --export-dynamic-symbol semantics to be compatible GNU ld 2.35

GNU ld from binutils 2.35 onwards will likely support
--export-dynamic-symbol but with different semantics.
https://sourceware.org/pipermail/binutils/2020-May/111302.html

Differences:

1. -export-dynamic-symbol is not supported
2. --export-dynamic-symbol takes a glob argument
3. --export-dynamic-symbol can suppress binding the references to the definition within the shared object if (-Bsymbolic or -Bsymbolic-functions)
4. --export-dynamic-symbol does not imply -u

I don't think the first three points can affect any user.
For the fourth point, Not implying -u can lead to some archive members unfetched.
Add -u foo to restore the previous behavior.

Exact semantics:

* -no-pie or -pie: matched non-local defined symbols will be added to the dynamic symbol table.
* -shared: matched non-local STV_DEFAULT symbols will not be bound to definitions within the shared object
  even if they would otherwise be due to -Bsymbolic, -Bsymbolic-functions, or --dynamic-list.
