armv8-sync-comp-swap.c: Replace 'do-require-effective-target' with 'dg-require-effective-target'.

2015-07-01  Matthew Wahab  <matthew.wahab@arm.com>

	* gcc.target/arm/armv8-sync-comp-swap.c: Replace
	'do-require-effective-target' with 'dg-require-effective-target'.
	* gcc.target/arm/armv8-sync-op-full.c: Likewise.
	* gcc.target/arm/armv8-sync-op-release.c: Likewise.
	* gcc.target/arm/armv8-sync-op-acquire.c: Likewise.  Also, replace
        'stlex' with 'strex' as the expected output.
