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.

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.

Update clang to use the InstrProfReader from LLVM to read
instrumentation based profile data. This also switches us from the
naive text format to the binary format, since that's what's
implemented in the reader.

The YAMLParser has its own escaped string representation, and does not
handle octal escape sequences. When writing the virtual file system to a
YAML file, use yaml::escape().

The idea is to give visibility to more type kinds, especially for getting
a better grasp of what appears as unexposed type kind with libclang.

Code review feedback from Eric Christopher on r204261.
I didn't want to go into too much detail (the revision history should
provide the full stuff) - but I can add more if that's preferred.
Also moved this up to right by the construction of the MCAsmInfo so
there's less chance that other things might sneak in in between.

For those playing at home this produced some fairly subtle behavior. The
sections created in InitMCObjectFileInfo were created without compressed
debug info (a mistake, but not necessarily /broken). Since these
sections were almost always referenced by the existing MCSection object,
this almost worked.
This got weird when we got to handling the relocations for a section.
See ELFObjectWriter::WriteSection where we compute the true section for
a relocation section by simply stripping the ".rela" prefix and then
looking up that section - doing so hit the compression codepath, looked
up .zdebug_blah and found a newly constructed empty section... thus,
things got weird.
This is untestable without a cross-project test (let me know if people
would prefer that to no testing).

These don't seem to have any real point. Let's start with
IndexingContext. I can't come up with any conceivable reason to have
many hundereds of thousands of these alive in an address space which
would make the 4x difference in allocated (but unused) memory for the
string scratch buffer a significant memory usage problem.
The EditedSource one is somewhat more surprising. This is an 8x increase
in the memory allocated (but not used) per editted source file. However,
for this to realistically be a problem, you would need to have over half
a million editted source files in a single address space, and even that
would only really have problems on 32-bit Windows where you really only
have 2gb of virtual address space. And what's more important, the fix to
this if it is actually an issue shouldn't be to shrink the allocator's
size, it is to pass a single allocator into *many* edited source file
objects and let them share the memory.
These were the only two uses of custom sized BumpPtrAllocators
(excluding ones in the JIT using a custom allocation strategy) in all of
LLVM, Clang, LLD, LLDB, or Polly. I don't think we actually need this
complexity in the primary BumpPtrAllocator at all and am planning to
remove it.

Because neither ' ' nor '-' is alphanumeric, \b won't match between them!
Since in this case we know our output is coming from a -### invocation,
we should always have spaces on both sides of the flag we're trying to match,
"-cc1".

This updates CodeGenPGO to use the ProfileDataReader introduced to
llvm in r203703 and the new API for writing out the profile introduced
to compiler-rt in r203710.

This is a reapplication of r203236 with modifications to the definition of attrs() and following the new style guidelines on auto usage.

An option with the same name already exists in the makefile build.
The name CLANG_IS_PRODUCTION is historical. We should probably change it, but
should change the configure build at the same time.
