Currently, we have no front-end type for ppc_fp128 type in IR. PowerPC target generates ppc_fp128 type from long double now, but there's option (-mabi=(ieee|ibm)longdouble) to control it and we're going to do transition from IBM extended double-double ppc_fp128 to IEEE fp128 in the future. This patch adds type __ibm128 which always represents ppc_fp128 in IR, as what GCC did for that type. Without this type in Clang, compilation will fail if compiling against future version of libstdcxx (which uses __ibm128 in headers). Although all operations in backend for __ibm128 is done by software, only PowerPC enables support for it. There's something not implemented in this commit, which can be done in future ones: - Literal suffix for __ibm128 type. w/W is suitable as GCC documented. - __attribute__((mode(IF))) should be for __ibm128. - Complex __ibm128 type.
