testsuite: arm: Check for short circuit instructions [PR103298]

Browse source 
Instead of checking that a certain transformation is not used by
counting the number of return instructions and the number of BEQ
instructions, check that none of CMP, MOV, ORR and AND instructions are
suffixed with EQ or NE.
Also removed size check as it's very unstable (depends on optimization
in use).

gcc/testsuite/ChangeLog:

	PR testsuite/103298
	* gcc.target/arm/pr43920-2.c: Change to assembler pattern
	"(cmp|mov|orr|and)(eq|ne)" for the check. Remove size check.
