tree-optimization/102572 - fix gathers with invariant mask
This fixes the vector def gathering for invariant masks which
failed to pass in the desired vector type resulting in a non-mask
type to be generate.

PR tree-optimization/102572
* tree-vect-stmts.c (vect_build_gather_load_calls): When
gathering the vectorized defs for the mask pass in the
desired mask vector type so invariants will be handled
correctly.
* g++.dg/vect/pr102572.cc: New testcase.
