re PR target/87532 (bad results from vec_extract(unsigned char, foo) dependent upon function inline)

gcc/ChangeLog:

2019-03-15  Kelvin Nilsen  <kelvin@gcc.gnu.org>

	PR target/87532
	* config/rs6000/rs6000-c.c (altivec_resolve_overloaded_builtin):
	When handling vec_extract, use modular arithmetic to allow
	constant selectors greater than vector length.
	* config/rs6000/rs6000.c (rs6000_expand_vector_extract): Allow
	V1TImode vectors to have constant selector values greater than 0.
	Use modular arithmetic to compute vector index.
	(rs6000_split_vec_extract_var): Use modular arithmetic to compute
	index for in-memory vectors.  Correct code generation for
	in-register vectors.
	(altivec_expand_vec_ext_builtin): Use modular arithmetic to
	compute index.
