[X86] matchAddressRecursively - don't fold zext(shl(x,c)) -> shl(zext(x),c)) if the pattern has multiple uses
Fixes #97533 crash where we hit a case where the root node had referenced the original zext node, which we then deleted - hopefully I can come up with a better solution, but the codegen changes don't look too bad atm (pulls out a shift from some complex LEA nodes that shared the scaled index).
