Verify we don't have any vector temporaries in the IL at least until
ISEL which may introduce VEC_EXTRACTs on targets which support
non-constant indices (see PR116421).
As a pass I chose NRV for no particular reason except that it is
literally the last pass prior ISEL. At least at time of writing this.
gcc/testsuite/ChangeLog:
* c-c++-common/vector-subscript-4.c: Check for vectors prior
ISEL.

Ok for mainline?
