qiucf added a parent revision: D81669: [PowerPC] Support constrained fp operation for scalar sitofp/uitofp.

D70867 <https://reviews.llvm.org/D70867> introduced support for expanding most `ppc_fp128` operations. But `sitofp/uitofp` is missing. This patch adds that after D81669 <https://reviews.llvm.org/D81669>.

Note: There's still issue about chain for `ppc_fp128` on SPE subtargets. But I'm not sure if the type is fully supported on SPE.
