Support __seg_fs and __seg_gs on x86
Summary:
GCC supports named address spaces macros:
https://gcc.gnu.org/onlinedocs/gcc/Named-Address-Spaces.html
clang does as well with address spaces:
https://clang.llvm.org/docs/LanguageExtensions.html#memory-references-to-specified-segments
Add the __seg_fs and __seg_gs macros for compatibility with GCC.
