Fangrui Song 23023654be [libc++] Replace __ppc64__ with __powerpc64__ and fix is_iec559 for non-ibm128 ... The lowercase `__ppc64__` is not defined by non-darwin powerpc64 GCC, therefore it lures users to write code which is not portable to GCC. Migrate to `__powerpc64__` in preparation for undefining `__ppc64__`. `__powerpc64__` is much more common than `__PPC64__`. Update alignment_of.pass.cpp to use 1 unconditionally: on powerpc-unknown-linux-gnu `alignof(bool) = _Alignof(bool) = __alignof(bool) = 1`. The value 4 might be derived from an ancient Clang. Change is_iec559 to true when long double uses uses IEEE 754 quadruple or double precision (i.e. not ibm128).
