The following adds missing verification that the input vectors
have the same number of elements for vectorizable_operation.
Bootstrapped and tested on x86_64-unknown-linux-gnu, pushed.

* tree-vect-stmts.cc (vectorizable_operation): Check that
the input vectors have the same number of elements.
* gcc.dg/torture/pr105132.c: New testcase.
