[TargetLowering] Use legally typed shifts to split chunks in expandDIVREMByConstant. (#187567)
This replaces LegalVT with HiLoVT and LegalWidth with HBitWidth as
they are the same for all current uses.
    
Then we rewrite the shifts to operate on LL and LH.
    
There's a slight regression on RISC-V due to different node creation
order leading to different DAG combine order. I have other refactoring
I'd like to explore then I may try to fix that.
