Evgeniy Stepanov 48af2a9e66 Fix -mfpu parsing on ARM.
- Support gcc-compatible vfpv3 name in addition to vfp3.
- Support vfpv3-d16.
- Disable neon feature for -mfpu=vfp* (yes, we were emitting Neon instructions
  for those!).

Chandler Carruth c89aa9d964 Add support for the androideabi environment to our triple support, and
for the arm-linux-androideabi triple in particular.

Also use this to do a better job of selecting soft FP settings.

Eric Christopher fc3ee566eb Add -g to the cc1as flags only if we're dealing with an original
source file. Otherwise -g -save-temps will error out on the compile
of any .c file.

Fixes about 4000 of the errors in the clang-tests gdb test suite.

Douglas Gregor 2f197adeeb Rename the command-line option for mapping #include/#import over to
module imports from -fauto-module-import to -fmodules. The new name
will eventually be used to enable modules, and the #include/#import
mapping is a crucial part of the feature.

Chandler Carruth 306bd2c6aa Fix PR11685 by implementing -ffast-math and its various friends in the
Clang driver. This involves a bunch of silly option parsing code to try
to carefully emulate GCC's options. Currently, this takes a conservative
approach, and unless all of the unsafe optimizations are enabled, none
of them are. The fine grained control doesn't seem particularly useful.
If it ever becomes useful, we can add that to LLVM first, and then
expose it here.

This also fixes a few tiny bugs in the flag management around
-fhonor-infinities and -fhonor-nans; the flags now form proper sets both
for enabling and disabling, with the last flag winning.

I've also implemented a moderately terrifying GCC feature where
a language change is also provided by the '-ffast-math' flag by defining
the __FAST_MATH__ preprocessor macro. This feature is tracked and
serialized in the frontend but it isn't used yet. A subsequent patch
will add the preprocessor macro and tests for it.

I've manually tested that codegen appears to respect this, but I've not
dug in enough to see if there is an easy way to test codegen options w/o
relying on the particulars of LLVM's optimizations.

Chandler Carruth 1fc603e516 Split the Windows toolchain definition into its own file. This is
especially nice as the Windows toolchain needs the windows header files,
and has lots of platform specific hooks in it.

To facilitate the split, hoist a bunch of file-level static helpers into
class-level static helpers. Spiff up their doxygen comments while there
as they're now more likely to be looked up via docs.

Hopefully, this will be followed by further breaking apart of the
toolchain definitions. Most of the large and complex ones should likely
live on their own. I'm looking at you Darwin. ;]

fails within a call to a constexpr function. Add -fconstexpr-backtrace-limit
argument to driver and frontend, to control the maximum number of notes so

APValue types, and move the testing for this functionality from a unittest to
a -verify test now that it's visible in clang's output.

Richard Smith 9a56882e53 Add driver arguments -ftemplate-depth=N and -fconstexpr-depth=N, with the same
semantics and defaults as the corresponding g++ arguments. The historical g++
argument -ftemplate-depth-N is kept for compatibility, but modern g++ versions
no longer document that option.

Add -cc1 argument -fconstexpr-depth N to implement the corresponding
functionality.

The -ftemplate-depth=N part of this fixes PR9890.
