Adam Nemet 1eea3e577d Reapply r281276 with passing -emit-llvm in one of the tests
Original commit message:

Add -fdiagnostics-show-hotness

Summary:
I've recently added the ability for optimization remarks to include the
hotness of the corresponding code region.  This uses PGO and allows
filtering of the optimization remarks by relevance.  The idea was first
discussed here:
http://thread.gmane.org/gmane.comp.compilers.llvm.devel/98334

The general goal is to produce a YAML file with the remarks.  Then, an
external tool could dynamically filter these by hotness and perhaps by
other things.

That said it makes sense to also expose this at the more basic level
where we just include the hotness info with each optimization remark.
For example, in D22694, the clang flag was pretty useful to measure the
overhead of the additional analyses required to include hotness.
(Without the flag we don't even run the analyses.)

For the record, Hal has already expressed support for the idea of this
patch on IRC.

Richard Smith b6a3b4ba61 Add a mode to clang-tblgen to generate reference documentation for warning and
remark flags. For now I'm checking in a copy of the built documentation, but we
can replace this with a placeholder (as we do for the attributes reference
documentation) once we enable building this server-side.

Sjoerd Meijer 0a8d4216ad This adds new options -fdenormal-fp-math and passes through option -ffast-math
to CC1, which are translated to function attributes and can e.g. be mapped on
build attributes FP_exceptions and FP_denormal. Setting these build attributes
allows better selection of floating point libraries.

Manman Ren 11f2a47772 Module: add -fprebuilt-module-path to support loading prebuilt modules.
In this mode, there is no need to load any module map and the programmer can
simply use "@import" syntax to load the module directly from a prebuilt
module path. When loading from prebuilt module path, we don't support
rebuilding of the module files and we ignore compatible configuration
mismatches.

Aaron Ballman 4f6b3ecfd2 Despite there being an option, it seems that Sphinx has decided that "=123" is part of the option directive name, and so having "=0" in the option tag is problematic. Since the option tag is part of the option directive definition, it's superfluous, and so I've removed it.
