Update fuzzing test to comply with new optimisation.

https://reviews.llvm.org/D125933 improved some of LLVM's handling of
binary ORs, which meant we have one less conditional branch, because the
'if (Size > 5 && Data[5] == 'R')' and 'if (bits == 63)' branches are now
correctly folded.

Fix up fuzzing test on Windows.

3bd112c720dc fixed the fuzzing test on Linux, which, after
https://reviews.llvm.org/D125933, has one less branch. Turns out, on
Windows, that it still has the extra branch. I'm guessing that's because
exit() isn't known to be noreturn on Windows or something.

Either way, just make the test more tolerant.

This partially reverts commit e8cae487022c2216182ae1ec24f248f287a614b7.
Changes since that commit:
 - Use `SourceManager::isBeforeInTranslationUnit` instead of the fancy
   decomposed decl logarithmic search.
 - Add a test for including a system header containing a deprecated
   include.
 - Add `REQUIRES: system-linux` clause to the test.

[clang-tidy] Introduce the WarnIntoHeaders option to modernize-deprecated-headers

Unfortunately, we must restrict the checker to warn for deprecated headers
only if the header is included directly from a c++ source file.

For header files, we cannot know if the project has a C source file
that also directly/indirectly includes the offending header file
otherwise. Thus, it's better to be on the safe side and suppress those
reports.

One can opt-in the old behavior, emitting diagnostics into header files,
if one explicitly sets the WarnIntoHeaders=true, in which case nothing
will be changed.

Add a page to track C defect report status

We currently have a page for tracking defects against the C++ standard,
but we don't have the same information for the C standard. This starts
us down the path of being able to track that in a way our users can see.

There are *a lot* of entries marked as "Unknown". As we validate
Clang's behavior for a given DR by adding a test case for it, we can
slowly begin to improve this page over time.

This page is now linked from the existing C status page, which was
updated slightly as a result of these changes as well.

Note, unlike with the C++ defect report page, this content is not auto-
generated from a source document and is not automatically updated from
test comments. It may be worthwhile to automate the updates based on
our test coverage, but that can happen later.

[OpenMP] Fix partial unrolling off-by-one.

Even though the comment description is ".unroll_inner.iv < NumIterations", the code emitted a BO_LE ('<=') operator for the inner loop that is to be unrolled. This lead to one additional copy of the body code in a partially unrolled. It only manifests when the unrolled loop is consumed by another loop-associated construct. Fix by using the BO_LT operator instead.

The condition for the outer loop and the corresponding code for tiling correctly used BO_LT already.

[lldb] Consider binary as module of last resort

When setting an address breakpoint using a non-section address in lldb
before having ever run the program, the binary itself is not considered
a module. As a result, the breakpoint is unresolved (and never gets
resolved subsequently).

This patch changes that behavior: as a last resort, the binary is
considered as a module when resolving a non-section address breakpoint.

[lldb] Fix spurious assertion in PrintCommandOutput

When the string passed to PrintCommandOutput doesn't end with a newline,
`written` will exceed `size` and result in an lldbassert.

After 8e776bb660dda6c51ce7ca6cea641db1f47aa9cf we don't really need
written anymore and we can check whether `str` is empty instead. This
patch simplifies the code and removes the assert that's no longer
relevant.

[LLVM] Add a check if should cast atomic operations to integer type

Currently for atomic load, store, and rmw instructions, as long as the
operand is floating-point value, they are casted to integer. Nowadays many
targets can actually support part of atomic operations with floating-point
operands. For example, NVPTX supports atomic load and store of floating-point
values. This patch adds a series interface functions `shouldCastAtomicXXXInIR`,
and the default implementations are same as what we currently do. Later for
targets can have their specialization.
