[libcxx] Fix definition of regex_traits::__regex_word on big-endian glibc systems Summary: On glibc, the bits used for the various character classes is endian dependant (see _ISbit() in ctypes.h) but __regex_word does not account for this and uses a spare bit that isn't spare on big-endian. On big-endian, it overlaps with the bit for graphic characters which causes '-', '@', etc. to be considered a word character. Fixed this by defining the value using _ISbit(15) on MIPS glibc systems. We've restricted this to MIPS for now to avoid the risk of introducing failures in other targets. Fixes PR26476.
