[PATCH] D40673: Add _Float128 as alias to __float128 to enable compilations on Fedora27/glibc2-26

mibintc added a comment.

I responded to comments from @eli.friedman and @hubert.reinterpretcast : I added  FIXME comment regarding the "Q" suffix on the float 128 literals (gcc uses https://reviews.llvm.org/F128 but clang doesn't support this).  Hubert pointed out that the floating point macros should only be enabled when float128 is enabled, so I added a check before defining them. I fixed a couple problems that Hubert pointed out in the test case.
