Can this be split up? Seems like some of this could be done in independent changes. Like changing LMUL layout. Changing loads. Changing madc.



================
Comment at: llvm/lib/Target/RISCV/AsmParser/RISCVAsmParser.cpp:2310
-        Opcode == RISCV::VSBC_VXM || Opcode == RISCV::VFMERGE_VFM ||
-        Opcode == RISCV::VMERGE_VIM || Opcode == RISCV::VMERGE_VVM ||
-        Opcode == RISCV::VMERGE_VXM)
----------------
Why is this being dropped? This was a bug fix I just earlier this week. I don't think vmerge can ever V0 as a destination and the parser previously crashed on it.
