rs6000/test: Adjust some test cases on partial vector [PR96373]

Browse source 
As Richard pointed out in [1] and the testing on Power10, the
proposed fix for PR96373 requires some updates on a few rs6000
test cases which adopt partial vector.  This patch is to fix
all of them with one extra option "-fno-trapping-math" as
Richard suggested.

Besides, the original test case also failed on Power10 without
Richard's proposed fix, this patch adds it together for a bit
better testing coverage.

	PR target/96373
