[RISCV] Define vector widening type-convert intrinsic.

[monkchiang]

Summary

Define intrinsics:

1. vfwcvt.xu.f.v/vfwcvt.x.f.v
2. vfwcvt.rtz.xu.f.v/vfwcvt.rtz.x.f.v
3. vfwcvt.f.xu.v/vfwcvt.f.x.v
4. vfwcvt.f.f.v

We work with @rogfer01 from BSC to come out this patch.

Do these instructions need earlyclobber?

llvm/include/llvm/IR/IntrinsicsRISCV.td

The destination vector type isn't the same as the first source vector so this comment seems wrong

407

Same here

llvm/lib/Target/RISCV/RISCVInstrInfoVPseudos.td

261

Why can't we just list the float types as the second argument here instead of needing use GetFloatVTypeInfo?

[monkchiang]

address @craig.topper 's comments, and rebase the patch.
thanks!

This is unneeded now.

1283

Why are we removing this blank line?

llvm/test/CodeGen/RISCV/rvv/vfwcvt-f-f-rv32.ll

2

Float to double is missing from rv32.

llvm/test/CodeGen/RISCV/rvv/vfwcvt-f-x-rv32.ll

2

i32 to double is missing

llvm/test/CodeGen/RISCV/rvv/vfwcvt-f-xu-rv32.ll

2

i32 to double is missing

[monkchiang]

Remove unneeded class, and Add several missing test cases for RV32.
All of mask test cases follow-up D93878.

[monkchiang]

Remove i64 to float in RV32 test case for fwcvt.xu.f.v/fwcvt.x.f.v/fwcvt.rtz.xu.f.v/fwcvt.rtz.x.f.v intrinsic.

[craig.topper]

LGTM

[craig.topper]

I don't think my earlyclobber question from earlier was addressed?

[monkchiang]

1. Add earlyclobber constraint
2. vfwcvt.f.xu and vfwcvt.f.x support i8 to float16 conversion
3. Add new test cases for vfwcvt.f.xu and vfwcvt.f.x

Sorry, I didn't see this comment until you noticed.
