Subject: [PATCH] Partial backport r256656

2018-06-15  Martin Liska  <mliska@suse.cz>

	Backport from mainline
	2018-01-10  Kelvin Nilsen  <kelvin@gcc.gnu.org>

	* lex.c (search_line_fast): Remove illegal coercion of an
	unaligned pointer value to vector pointer type and replace with
	use of __builtin_vec_vsx_ld () built-in function, which operates
	on unaligned pointer values.
