FileManager::invalidateCache is not safe to call when there may be
existing references to the file. What module load failure needs is
to refresh so stale stat() info isn't stored.
This may be the last user of invalidateCache; I'll take a look and
remove it if possible in a future commit.
This caused a use-after-free error as well as a spurious error message
that a module was "found in both 'X.pcm' and 'X.pcm'" in some cases.

The list of alpha and the list of implicit checkers added. An ability to expand/collapse long texts added. Markup fixed.

The cost model conservatively assumes that it will always get scalarized and
that's about as good as we can get with the generic TTI; reasoning whether a
shuffle with an efficient lowering is available is hard. We can override that
conservative estimate for some targets in the future.

- On ARM/ARM64 we get a vrev because the shuffle matching code is really smart. We still unroll anything that's not v4i32 though.
- On X86 we get a pshufb with SSSE3. Required more cleverness in isShuffleMaskLegal.
- On PPC we get a vperm for v8i16 and v4i32. v2i64 is unrolled.

When we were padding a struct to avoid splitting it between registers and
the stack, we were throwing away the type which the argument should be coerced
to.

Summary:
Sandboxed code may now pass additional arguments to
__sanitizer_sandbox_on_notify() to force all coverage data to be dumped to a
single file (the default is one file per module). The user may supply a file or
socket to write to. The latter option can be used to broker out the file writing
functionality. If -1 is passed, we pre-open a file.

Checks that at at least qRegisterInfo0 responds with a valid
register info reply packet. The packet is parsed and validates
that all keys come from the documented set of valid keys. It
then validates that a minimum set of expected keys
are present in the returned packet.
This test is set to pass on debugserver and fail on llgs TOT.
llvm-svn: 209109
debugserver now returns $X09 as the immediate response to
a $k kill process request rather than $W09.
ProcessGDBRemote now properly handles X as indication of
a process exit state.
The @debugserver_test and @lldb_test for $k now properly expects
an X notification (signal-caused exit) after killing a just-attached
inferior that was still in the stopped state.

SVN r209103 removed the OwningPtr variant of the MemoryBuffer APIs. Switch to
the equivalent std::unique_ptr versions. This should clear up the build bots.
llvm-svn: 209104
r179585 introduced different MSPropertyRefExpr visitation for RAV and DRAV that
appears to have been unintentional. Let's use the more complete one.
llvm-svn: 209101
The instrprofile-write-file-only test was failing on the builtbots. The runtime
library initialization is explicitly being discarded to avoid the atexit hook.
However, this would also prevent the filename from being initialized. Thus,
when the write file was invoked, the filename would not be setup, and the test
would fail as the profiling data would never be written out. Explicitly
initialize the filename to ensure that the data is written out when requested.
This should hopefully finally get the build bots all green again.
llvm-svn: 209099
dlopen expects that the flags contains RTLD_LAZY or RTLD_NOW. RTLD_LAZY will
resolve the symbol on first use, and is generally preferred due to efficiency.
Add this to fix the test failure on the build bots.
llvm-svn: 209098
Add logging to report any failures that may occur on calls to libdl. Without
this, it is difficult to identify the actual problem if the test fails.
llvm-svn: 209097
Add an explicit link against libdl. libdl may not be indirectly pulled on some
Linux hosts. Explicitly link against it. This should hopefully improve the
state of the build bots.

Extend the function definition macros further to support COFF object emission.
The function definition in COFF includes the type and storage class in the
symbol definition context. This is needed to make the assembly routines
possible to be built for COFF environments (i.e. Windows).
llvm-svn: 209095
Rename the HIDDEN_DIRECTIVE macro to HIDDEN and give it a parameter providing
the name of the symbol to be given hidden visibility. This makes the macros
more amenable to COFF.

* Shuffle around code to reduce delta between the two RAVs.
* Merge r189185 that was applied only to one of the RAVs and became apparent during the unification work.
* Fix Enqueue data recursion typo.
Our delta is down to +-579!
llvm-svn: 209093
Apply current ToT clang-format on the two RAVs to reduce delta and help
identify differences between the two.
We lose a little pretty formatting in the headers but that's the price to pay
so we can diff these two files effectively and look to a future where we don't
have to maintain two copies of this code.
Formatting and whitespace only.
llvm-svn: 209092
Define a macro to reduce the delta between RecursiveASTVisitor and
DataRecursiveASTVisitor.
Some years ago, someone thought it was a good idea to copy the entire RAV to
support cursor visitation in libclang.
Since then the two have diverged needlessly and the rest is history.
This series of commits aims to reduce delta between the two so that we can
reason about their differences, apply bugfixes that were only made to one but
not the other, and ultimately find a way to unify two two chunks of code.
