[Bug target/112648] RISC-V Vector parameter riscv-autovec-lmul value is ineffective

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=112648 --- Comment #3 from Jeremy Bennett --- Following a discussion on the weekly call, it seems that I have misunderstood the purpose of this parameter. It seems it is a hint to the optimizer that a particular LMUL value is most efficient, not as a m
