re PR tree-optimization/64024 (gcc.dg/vect/vect-simd-clone-6.c ICEs)

	PR tree-optimization/64024
	* tree-vectorizer.h (struct _stmt_vec_info): Remove simd_clone_fndecl
	field.  Add simd_clone_info field.
	(STMT_VINFO_SIMD_CLONE_FNDECL): Remove.
	(STMT_VINFO_SIMD_CLONE_INFO): Define.
	* tree-vect-stmts.c (vectorizable_simd_clone_call): Adjust for
	STMT_VINFO_SIMD_CLONE_FNDECL becoming first element of
	STMT_VINFO_SIMD_CLONE_INFO vector.  For linear arguments, remember
	base and linear_step from analysis phase and use it during transform
	phase, biased by the difference between LOOP_VINFO_NITERS{_UNCHANGED,}
	multiplied by linear_step.
	(free_stmt_vec_info): Release STMT_VINFO_SIMD_CLONE_INFO.

	* gcc.dg/vect/vect-simd-clone-13.c: New test.
	* gcc.dg/vect/vect-simd-clone-14.c: New test.
