The following fixes the vector type registered for external defs
in call arguments when vectorizing with SLP. We assumed uniform
vectype_in types here but with calls like .COND_MUL we also have
mask arguments which, when invariant or external, need to have
a proper mask vector type.
Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed.

* tree-vect-stmts.c (vectorizable_call): Properly use the
per-argument determined vector type for externals and
invariants.
