Wasm fmuladd relaxed (#163177)
Reland #161355, after fixing up the cross-projects-tests for the wasm
simd intrinsics.
Original commit message:
Lower v4f32 and v2f64 fmuladd calls to relaxed_madd instructions.
If we have FP16, then lower v8f16 fmuladds to FMA.
I've introduced an ISD node for fmuladd to maintain the rounding
ambiguity through legalization / combine / isel.
