[mlir][LLVMIR] Add support for translating FCmp & more FP constants

Authored by myhsu on Apr 28 2022, 11:37 AM.



This patch add supports for translating FCmp and more kinds of FP constants in addition to 32 & 64-bit ones. However, we can't express ppc_fp128 constants right now because the semantics for its underlying APFloat is S_PPCDoubleDouble but mlir::FloatType doesn't support such semantics.
