Summary:
Correct size_t to be unsigned int and ptrdiff_t to be signed long. The types were the correct size before this change but
the exact type matters for name mangling and exception handling in C++.

A CursorPlatformAvailability can have several "unavailable" attributes, don't
leak all but the first. I'm not sure if there can be several "deprecate"ds too,
but add the same logic there to keep the two code paths looking the same.

The result of getBufferForFile() must be freed.
(Should we change functions that expect the caller to assume ownership so
that they return unique_ptrs instead? Then the type system makes sure we get
this right.)

together. This is extremely hairy, because in general we need to have loaded
both the template and the pattern before we can determine whether either should
be merged, so we temporarily violate the rule that all merging happens before
reading a decl ends, but *only* in the case where a template's pattern is being
loaded while loading the template itself.
In order to accomodate this for class templates, delay loading the injected
class name type for the pattern of the template until after we've loaded the
template itself, if we happen to load the template first.

it could have been.

Otherwise including a header in your source file that is not included by
framework's umbrella header will silently add an empty submodule with that
name.

@import Foo.NotInModule;
which then would have succeeded because the inferred module map
contained an empty submodule called NotInModule.

We were using the same guard variable and failing to initialize the
second global.
Clang is still not MS ABI compatible in this area. Fixing that is
PR16959, which will require LLVM changes to @llvm.global_ctors.

Summary:
This documents the usage of sample profilers with Clang and the
profile format expected by LLVM's optimizers. It also documents the
profile conversion tool used by Linux Perf.

The original messages were:
"Driver: Honor %INCLUDE% when built with MinGW"
"Add missing test triples"
The test was still failing on OS X.

We previously treated ARM separately from the generic Itanium ABI for
initializing guard variables. This code duplication led to things like
the ARM path missing the memory barrier for threadsafe handling, and a
highly misleading comment about how we were (mis)using the generic ABI
for ARM64 when really it went through the ARM codepath.
This unifies the two code paths. Functionally, this changes the ARM
and ARM64 codepath to use one byte loads instead of 4 and 8,
respectively, and adds the missing atomic acquire to these loads.
Other architectures are unchanged.

Users are expected to pass system includes through the INCLUDE
environment variable on Windows. There's no reason to change behavior
based on the toolchain used to build Clang.
I didn't change the registry searching code because I'm not sure it
builds with mingw and I'm not set up to test it.

We don't need the ASTContext for the diagnostics, only the language
options, which we can get from the compiler invocation. It worries me
how many categorically different states the ASTUnit class can be in
depending on how it is being constructed/used.

-Wc++11-compat-deprecated-writable-strings. It's neither a C++11 compatibility

Summary:
This allows callers of Diags.Report() to append a value to the name of
the flag associated with the diagnostic. This is useful in cases like
the -Rpass flag, where we want the diagnostic to show the name of the
pass that matched the pattern. Instead of showing "... [-Rpass]", this
allows us to show "... [-Rpass=passname]".

Unlike the standard AAPCS64 ABI, variadic arguments are always passed on the
stack with the Darwin ABI, and this was not being considered when deciding
whether to expand HFA/HVA arguments in a call. An HFA argument with a "float"
base type was being expanded into separate "float" arguments, each of which
was then extended to a double, resulting in a serious mismatch from what is
expected by the va_arg implementation. <rdar://problem/15777067>

This test didn't work as intended and was ultimately disabled some years ago in
r169458.
Indeed it's not clear if the '\n' was ever passed through to the driver
correctly given that lit would insert '&& {' at the newline.
Test rewritten to use printf/xargs to insert '\n' in a more reliable manner and
