Herald added a project: LLVM.

PowerPC supports type `ppc_fp128`, which is not IEEE floating type and
for this type llvm.is_fpclass cannot be lowered with generic code. This
change implements custom lowering for `ppc_fp128`.

The change was tested using runtime tests from https://reviews.llvm.org/D112933
and the change of clang https://reviews.llvm.org/D112932.
