[PATCH, ARM, testsuite] Improve scd42-1.c for UAL

[Tony Liu]

Hi,

This is the patch to improve the test case gcc.target/arm/scd42-1.c for both
UAL and non-UAL. It now checks UAL format assembly code for Thumb1 and
Thumb2 while non-UAL format assembly code for ARM mode.

With this patch, the test passes for both cases.

Thanks,
Tony
