[RISCV] Convert LWU to LW if possible in RISCVOptWInstrs (#144703) 
After the refactoring in #149710 the logic change is trivial.

Motivation for preferring sign-extended 32-bit loads (LW) vs
zero-extended (LWU):
* LW is compressible while LWU is not.
* Helps to minimise the diff vs RV32 (e.g. LWU vs LW)
* Helps to minimise distracting diffs vs GCC. I see this come up
frequently when comparing GCC code and in these cases it's a red
herring.

Similar normalisation could be done for LHU and LH, but this is less
well motivated as there is a compressed LHU (and if performing the
change in RISCVOptWInstrs it wouldn't be done for RV32). There is a
compressed LBU but not LB, meaning doing a similar normalisation for
byte-sized loads would actually be a regression in terms of code size.
Load narrowing when allowed by hasAllNBitUsers isn't explored in this
patch.

This changes ~20500 instructions in an RVA22 build of the
llvm-test-suite including SPEC 2017. As part of the review, the option
of doing the change at ISel time was explored but was found to be less
effective.
