Subject: sjlj.S (CONCAT1, [...]): Respond to __USER_LABEL_PREFIX__ for targets
 that use it.

libitm:

	* config/x86/sjlj.S (CONCAT1, CONCAT2, SYM): Respond to
	__USER_LABEL_PREFIX__ for targets that use it.
	TYPE, SIZE, HIDDEN): New macros to assist on non-elf targets.
	(_ITM_beginTransaction): Use SYM, TYPE, SIZE macros to assist
	in portability to non-elf targets.
	(GTM_longjmp): LIkewise.
	* libitm_i.h (begin_transaction): Apply __USER_LABEL_PREFIX__
	where required.
