re PR tree-optimization/24659 (Conversions are not vectorized)

	PR tree-optimization/24659
	* tree-vect-transform.c (vectorizable_call): Handle
	(nunits_in == nunits_out / 2) and (nunits_out == nunits_in / 2) cases.

	* config/i386/sse.md (vec_pack_sfix_v2df): New expander.
	* config/i386/i386.c (enum ix86_builtins)
	[IX86_BUILTIN_VEC_PACK_SFIX]: New constant.
	(struct bdesc_2arg) [__builtin_ia32_vec_pack_sfix]: New builtin
	description.
	(ix86_init_mmx_sse_builtins): Define all builtins with 2 arguments as
	const using def_builtin_const.
	(ix86_expand_binop_builtin): Remove bogus assert() that insn wants
	input operands in the same modes as the result.
	(ix86_builtin_vectorized_function): Handle BUILT_IN_LRINT.

testsuite/ChangeLog:

	PR tree-optimization/24659
	* gcc.target/i386/vectorize2.c: New test.
	* gcc.target/i386/sse2-lrint-vec.c: New runtime test.
	* gcc.target/i386/sse2-lrintf-vec.c: Ditto.
