The function ends up getting called on VECTOR_TYPEs which it
really isn't prepared for and with the TYPE_PRECISION checking
changes will ICE. The following exits early when the type
to work on isn't scalar integral.
Bootstrap and regtest ongoing on x86_64-unknown-linux-gnu, will
push after that finished.
* tree-vect-patterns.cc (vect_look_through_possible_promotion):
Exit early when the type isn't scalar integral.
