Handle vectors that don't fit in an integer.
GCN vector sizes range between 64 and 512 bytes, none of which have
correspondingly sized integer modes. This breaks a number of assumptions
throughout the compiler, but I don't really want to create modes just for this
purpose.
Instead, this patch fixes up the cases that I've found, so far, such that the
compiler tries something else, or fails to optimize, rather than just ICE.

* tree-vect-stmts.c (vectorizable_store): Don't ICE when
int_mode_for_size fails.
(vectorizable_load): Likewise.
