Handle poly_int vector sizes in get_vec_alignment_for_array_type
get_vectype_for_scalar_type returns a variable-length vector type
for SVE, whereas get_vec_alignment_for_array_type assumed it would
always be an INTEGER_CST.
This is needed to build libstdc++-v3/src/closures.cc for SVE
(and probably many other places besides -- this was just the
first hit).
