Instead of directly linking to ppcg's main source directory, we link to the
parent director. This allows us to access ppcg's include files with
'ppcg/cuda.h' and avoids a conflict with NVIDIA's cuda.h header.
Also drop an include directory that is currently not used.

A sequence of CHECK lines allows additional statements to appear in the
output of the tested program without any test failures appearing. As we do
not want this to happen, switch this test case to use CHECK-NEXT.

This patch adds the check for specifying both simdlen and safelen clauses on the 'distribute simd' or 'distribute parallel for simd' constructs.

In a linker script, `.` is a special symbol indicating a counter.
Previously, we had two expression types, ExprKind and SymbolAssignmentKind
for `.` and all the other symbol names, respectively. But we could merge
them because the former is a special case of the latter.

Previously, it checked for the EC parameter and set HasError
only when there was an error. But in most places we called
error only when error had occurred, so this behavior was confusing.

Taking a lock before appending to a vector does no good unless threads
reading from the vector also take the lock, because the vector could be
re-sized.
I don't have a good isolated test for this. I found the issue with ASan
while testing a large project. I'm working on a bot that does this.

Writing `for (StringRef &SourceFile : ...)` is strange to begin with.
Subsequently capturing "SourceFile" by reference is even stranger. Just
copy the StringRef, since that's cheap to do.

Also stop trying to insert skip blocks at end_cf. This
was inserting them at the end of the block which doesn't make
sense. The skip should be inserted at the beginning of the block
right after the end cf. Just remove this for now since no tests
seem to stress this and I think this can be handled more generally
later.

This changes the CompilerInstance::createOutputFile function to return
a std::unique_ptr<llvm::raw_ostream>, rather than an llvm::raw_ostream
implicitly owned by the CompilerInstance. This in most cases required that
I move ownership of the output stream to the relevant ASTConsumer.
The motivation for this change is to allow BackendConsumer to be a client
of interfaces such as D20268 which take ownership of the output stream.

Add an option to opt into compiler-rt instead of libgcc. This option defaults
to OFF to avoid a behaviour change. It is not possible to mix and match
different runtime libraries. Disabling this requires that libc++ is built
accordingly. This knob is particularly useful for targets that are GCC by
default (i.e. Linux).

If a subtarget has both ZCZeroing and CustomCheapAsMoveHandling features (now
only Kryo has both), set COPY (W|X)ZR isAsCheapAsAMove.

For a fully inlined call chain like a -> b -> c -> d, we were emitting
line info for 'd' 3 separate times: once for d's actual InlineSite line
table, and twice for 'b' and 'c'. This is particularly inefficient when
all these functions are in different headers, because now we need to
encode the file change. Windbg was coping with our suboptimal output, so
this should not be noticeable from the debugger.

We don't need to print any of the special __mh_*_header symbols when
disassembling. Since they point at the beginning of the segment (not where the
actual code is) they're pretty misleading.
Should also fix lld bots.

This improves the situation discussed in D19228 where we were forcing VPERMPD/VPERMQ where VPERM2F128/VPERM2I128 would have been better.
This was incorrectly reverted in rL275421 during triage of PR28552.

There is not enough padding in front of memchr(), and, the first 6 bytes
contains a branch instruction. Basically the current interception will
not work on memchr().
It was disabled before, but was missing the part to disable it for
INTERCEPT_LIBRARY_FUNCTION.

Summary:
Both test have the same command-line.
The second test is missing the /GS-.
Keep in mind that /GS is on by default.

Summary:
The function wcslen is incorrectly hooked on windows 64-bits.
The interception library is not able to hook without breaking the code.
The function is too small and the interception must be done with
trampoline-hooking which turned out to be incorrect on a small
loop (first few instructions have a backedge).

We were quite happy to read past the end of the valid section data when
disassembling. Instead we entirely skip stub dylibs, and tell the user what's
happened if their section only has partial data.
