[PATCH][AARCH64]Make arm_align_max_stack_pwr.c and arm_align_max_pwr.c compile

testcase, instead of execution.

gcc/testsuite/

2015-09-03  Renlin Li  <renlin.li@arm.com>

	* gcc.target/aarch64/arm_align_max_pwr.c: Make it a compile test case,
	  check the assembly.
	* gcc.target/aarch64/arm_align_max_stack_pwr.c: Likewise.
