[4.6] Fix set-but-not-used warning [committed] (issue5013044)

[Diego Novillo]

The GCC version we use internally to build 4.6 treats unused variable
warnings as errors.  This was causing bootstraps to fail.

Tested on x86_64.  Committed to gcc-4_6-branch.


	* tree-vect-stmts.c (vect_transform_stmt): Remove unused
	local variable ORIG_SCALAR_STMT.
