Define MAX_CODE_ALIGN globally.

2018-07-17  Martin Liska  <mliska@suse.cz>

	* align.h (MAX_CODE_ALIGN): New.
	(MAX_CODE_ALIGN_VALUE): New.
	* common/config/i386/i386-common.c (ix86_handle_option):
	(MAX_CODE_ALIGN): Moved to align.h.
	* final.c (MAX_CODE_ALIGN): Likewise.
	* opts.c (parse_and_check_align_values):
	(MAX_CODE_ALIGN): Likewise.
	(MAX_CODE_ALIGN_VALUE): Likewise.
