[RISCV] Add support for matching .vx and .vi forms of binary instructions for fixed vectors.

[craig.topper]

Summary

Unlike scalable vectors, I'm only using a ComplexPattern for
the immediate itself. The vmv_v_x is matched explicitly. We igore
the VL argument when matching a binary operator, but we do check
it when matching splat directly.

I left out tests for vXi64 as they fail on rv32 right now.

[craig.topper]

Remove unused AVL operand from new tablegen classes.

clang-format:

4060

Minor typo: RISCInstrVInstrINfoVVL -> RISCVInstrInfoVVL

[craig.topper]

Fix capitalization in comment.

[craig.topper]

Rebase

[frasercrmck]

Could you perhaps explain why the splats (at least as non-roots) are matched like this and not with the existing complex patterns extended to also check VMV_V_X?

llvm/lib/Target/RISCV/RISCVInstrInfoVPseudos.td

4060

I think this has slipped back in after the rebase? RISCInstrVInstrINfoVVLPatterns.td should be RISCVInstrInfoVVLPatterns.td

[craig.topper]

Reuse the existing ComplexPatterns for the non-root case. The root case doesn't work because we need to match VL still.

[craig.topper]

Remove SplatIntOp.

[frasercrmck]

Cheers, LGTM.
