Sander de Smalen 84a4caeb84 [InstSimplify] Don't assume parent function when simplifying llvm.vscale. ...

D106850 introduced a simplification for llvm.vscale by looking at the
surrounding function's vscale_range attributes. The call that's being
simplified may not yet have been inserted into the IR. This happens for
example during function cloning.

This patch fixes the issue by checking if the instruction is in a
parent basic block.
