History
Simon Pilgrim 1ecc3d86ae [DAG] Enable ISD::SHL SimplifyMultipleUseDemandedBits handling inside SimplifyDemandedBits 
Pulled out of D77804 as its going to be easier to address the regressions individually.

This patch allows SimplifyDemandedBits to call SimplifyMultipleUseDemandedBits in cases where the source operand has other uses, enabling us to peek through the shifted value if we don't demand all the bits/elts.

The lost RISCV gorc2 fold shouldn't be a problem - instcombine would have already destroyed that pattern - see https://github.com/llvm/llvm-project/issues/50553
