testsuite: arm: Use check-function-bodies in cmse-5 tests

Converted the tests to use check-function-bodies in order to ensure that
the sequence is correct.
This also allows both APSR_nzcvq and APSR_nzcvqg as target selector does
not work when the -march and/or -mcpu overrides the target to test.

gcc/testsuite/ChangeLog:

	* gcc.target/arm/cmse/mainline/8m/hard-sp/cmse-5.c: Use
	check-function-bodies.
