[patch] Use dg-skip-if in several ARM testcases.

[Kazu Hirata]

Hi,

Attached is a patch to use dg-skip-if in several ARM testcases.

Without this patch, these testcases fail when multilib options
conflict with those options specified in dg-options.

Tested on arm-none-eabi.  OK to apply?

	* gcc.dg/arm-g2.c, gcc.dg/arm-mmx-1.c, gcc.dg/arm-scd42-2.c:
	Skip if the multilib testing specifies -march that does not
	agree with the one specified in the testcase.
