[InstCombine] Drop Range attribute when simplifying 'fshl' based on demanded bits (#124429)

When simplifying operands based on demanded bits, the return value range
of llvm.fshl might change. Keeping the Range attribute might cause
llvm.fshl to generate a poison and lead to miscompile. Drop the Range
attribute similar to `dropPosonGeneratingFlags` elsewhere.

Fix #124387
