UpdateTestChecks: sparc march handling

[lebedev.ri]

Summary

Another target that prefers to use -march in tests

llvm/test/CodeGen/SPARC$ grep -ri mtriple | wc -l
25
llvm/test/CodeGen/SPARC$ grep -ri march | wc -l
165

This test is being affected by a further patch,
so regenerate it to better visualize the changes
