[RISCV] Remove skipFunction from RISCVVMV0Elimination. (llvm#136080)

topperc · IanWood1 · commit 8cdc5ef7153e · 2025-05-06T08:50:46.000-07:00
skipFunction disables the pass for functions with optnone attribute.
This pass is important to correct register allocation so I don't think
it should be disabled.
