This patch adds stmt_vec_info to TARGET_SIMD_CLONE_USABLE to make sure the
target can reject a simd_clone based on the vector mode it is using.
This is needed because for VLS SVE vectorization the vectorizer accepts
Advanced SIMD simd clones when vectorizing using SVE types because the simdlens
might match.  This will cause type errors later on.

Other targets do not currently need to use this argument.

gcc/ChangeLog:

	* target.def (TARGET_SIMD_CLONE_USABLE): Add argument.
	* tree-vect-stmts.cc (vectorizable_simd_clone_call): Pass stmt_info to
	call TARGET_SIMD_CLONE_USABLE.
	* config/aarch64/aarch64.cc (aarch64_simd_clone_usable): Add argument
	and use it to reject the use of SVE simd clones with Advanced SIMD
	modes.
	* config/gcn/gcn.cc (gcn_simd_clone_usable): Add unused argument.
	* config/i386/i386.cc (ix86_simd_clone_usable): Likewise.
