forwprop: Ensure that shuffle masks are VECTOR_CSTs
As reported in PR118487, it is possible that the mask parameter
of a __builtin_shuffle() is not a VECTOR_CST.
If this is the case and checking is enabled then an ICE is triggered.
Let's add a check to fix this issue.
PR tree-optimization/118487
gcc/ChangeLog:
* tree-ssa-forwprop.cc (recognise_vec_perm_simplify_seq):
Ensure that shuffle masks are VECTOR_CSTs.
gcc/testsuite/ChangeLog:
* gcc.dg/tree-ssa/pr118487.c: New test.
