These functions are in the profile runtime. PGO comes later.
Unfortunately, there's only room for 16 characters in a Darwin section,
so use __llvm_prf_ instead of __llvm_profile_ for section names.

block as decl and type emission. This allows decl updates include statements
and expressions. No functionality change (but the generated PCM files are
incompatible with earlier versions of Clang).

Remove the remaining explicit static initialization from translation
units, at least on Darwin. Instead, create a use of __llvm_pgo_runtime,
which will pull in required code from compiler-rt.
After this commit (and its pair in compiler-rt), a user can define their
own __llvm_pgo_runtime to satisfy this undefined symbol and call the
functions in compiler-rt directly.

We were 'allowing' the following import
@import Sub;
where Sub is a subframework of Foo and we had a -F path inside
Foo.framework/Frameworks and no module map file for Sub. This would
later hit assertion failures in debug builds.
Now we should correctly diagnose this as a module not found error.

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".

Amends r204300 to not try to test fixing a wchar_t* to "%ls", which we don't
do correctly anyway. In C mode, wchar_t is just a typedef for a normal
primitive integer type, not a distinct type like it is in C++. To make this
work correctly, we'll need to look for the wchar_t typedef, not just the
builtin type.
Should fix the buildbots.

This change turns -fsanitize-memory-track-origins into
-fsanitize-memory-track-origins=[level] flag (keeping the old one for
compatibility). Possible levels are 0 (off), 1 (default) and 2 (incredibly
detailed). See docs (part of this patch) for more info.

The exception is return statements that include control-flow,
which are clearly doing something "interesting".
99% of the cases I examined for -Wunreachable-code that fired
on return statements were not interesting enough to warrant
being in -Wunreachable-code by default. Thus the move to
include them in -Wunreachable-code-return.
This simplifies a bunch of logic, including removing the ad hoc
logic to look for std::string literals.

This name, while more verbose, plays more nicely with tools that use
file extensions to determine file types. The existing spelling
'module.map' will continue to work, but the new spelling will take
precedence.
In frameworks, this new filename will only go in a new 'Modules'
sub-directory.
Similarly, add a module.private.modulemap corresponding to
module_private.map.

The spelling location of stringified strings is not a file location.
Optimally, we'll want to solve the problem (as the FIXME states) by
handing in the right FileEntry of the #include location.

The hash itself is still the number of counters, which isn't all that
useful, but this separates the API changes from the actual
implementation of the hash and will make it easier to transition to
the ProfileData library once it's implemented.

Since "half" is an OpenCL keyword and clang accepts __fp16 as an extension for
other languages, error messages and metadata (and hence debug info) should refer
to the half-precision floating point as "__fp16" instead of "half" when
compiling for non-OpenCL languages. This patch creates a new printing policy for
half in a similar manner to what is done for bool and wchar_t.

Test doesn't actually require production of an object file and for
some targets (e.g. hexagon) an assembler is not always available when
lit tests are run.

Due to not resetting the fake rparen data on the token when iterating
over annotated lines, we would pop the last element of the paren stack.
This patch fixes the underlying root cause, and makes the code more
robust against similar problems in the future:
- reset the first token when iterating on the same annotated lines due
to preprocessor branches
- never pop the last element from the paren stack, so we do not crash,
but rather incorrectly format
- add assert()s so we can figure out if our assumptions are violated
