Reid Kleckner 9eabbb6066 Enable __float128 for mingw for GCC compatibility and define __SIZEOF_FLOAT128__ on x86
GCC defines __FLOAT128__ on Power and __SIZEOF_FLOAT128__ on x86. We're
just following the inconsistency for now so users have some way to test.

Effectively merges this patch as requested by Martell Malone:

Nemanja Ivanovic bb1ea2d613 Enable support for __float128 in Clang and enable it on pertinent platforms
This patch corresponds to reviews:
http://reviews.llvm.org/D15120
http://reviews.llvm.org/D19125

It adds support for the __float128 keyword, literals and target feature to
enable it. Based on the latter of the two aforementioned reviews, this feature
is enabled on Linux on i386/X86 as well as SystemZ.
This is also the second attempt in commiting this feature. The first attempt
did not enable it on required platforms which caused failures when compiling
type_traits with -std=gnu++11.

If you see failures with compiling this header on your platform after this
commit, it is likely that your platform needs to have this feature enabled.

Nemanja Ivanovic d7d45bf8ce Revert 266186 as it breaks anything that includes type_traits on some platforms
Since this patch provided support for the __float128 type but disabled it
on all platforms by default, some platforms can't compile type_traits with
-std=gnu++11 since there is a specialization with __float128.
This reverts the patch until D19125 is approved (i.e. we know which platforms
need this support enabled).

Nemanja Ivanovic 50f29e06a1 Enable support for __float128 in Clang
This patch corresponds to review:
http://reviews.llvm.org/D15120

It adds support for the __float128 keyword, literals and a target feature to
enable it. This support is disabled by default on all targets and any target
that has support for this type is free to add it.

Based on feedback that I've received from target maintainers, this appears to
be the right thing for most targets. I have not heard from the maintainers of
X86 which I believe supports this type. I will subsequently investigate the
impact of enabling this on X86.

Nico Weber 08ef80f4b8 Rename test.cc files to test.cpp.
The lit.cfg files only add .cpp to suffixes, so these tests used to never run,
oops.  (Also tweak to of these tests in minor ways to make the actually pass.)
