clang-p2996/llvm/test/CodeGen/RISCV/half-convert.ll
Craig Topper d4ee84ceee [RISCV] Support FP_TO_S/UINT_SAT for i32 and i64. 
The fcvt fp to integer instructions saturate if their input is
infinity or out of range, but the instructions produce a maximum
integer for nan instead of 0 required for the ISD opcodes.

This means we can use the instructions to do the saturating
conversion, but we'll need to fix up the nan case at the end.

We can probably improve the i8 and i16 default codegen as well,
but I'll leave that for a follow up.
