[PATCH, tree-optimization]: Fix PR46142

Hello!

We have to enlarge dt array by one in vectorizable_call function to
accommodate extra function argument for FMA. Please also see the PR
[1].

For some reason, valgrind didn't catch this uninitialized situation,
but the one-liner patch is obvious.

	PR tree-optimization/46142
	* tree-vect-stmts.c (vectorizable_call): Enlarge dt array to
	accommodate third function argument.

Tested on x86_64-pc-linux-gnu {,-m32} and i686-pc-linux-gnu where the
patch fixes the failure.

Patch was committed to SVN mainline as obvious.
