testsuite: Fix TBAA in sse*and*p[sd]*.c tests

Browse Source 
This patch drops the no-strict-aliasing hack in m128-check.h and instead
ensures the tests read objects with the right dynamic type.

2021-01-26  Jakub Jelinek  <jakub@redhat.com>

	* gcc.target/powerpc/m128-check.h (CHECK_EXP): Remove
	optimize ("no-strict-aliasing") attribute.
	* gcc.target/powerpc/sse-andnps-1.c (TEST): Copy e into float[4]
	array to avoid violating TBAA.
	* gcc.target/powerpc/sse2-andpd-1.c (TEST): Copy e.d into double[2]
	array to avoid violating TBAA.
	* gcc.target/powerpc/sse-andps-1.c (TEST): Copy e.f into float[4]
	array to avoid violating TBAA.
	* gcc.target/powerpc/sse2-andnpd-1.c (TEST): Copy e into double[2]
	array to avoid violating TBAA.
