Fix x86_64-ism in selftest (PR bootstrap/78705) 

In r243317 I accidentally introduced an assumption in a selftest
in i386.c that Pmode == DImode.  This patch conditionalizes the
overzealous string comparison to avoid breaking the build on
32-bit i386.c targets.

gcc/ChangeLog:
	PR bootstrap/78705
	* config/i386/i386.c (selftest::ix86_test_dumping_memory_blockage):
	Conditionalize the string comparison on Pmode == DImode.
