[mips] Remove duplicate tests and add missing prefixes for *-LABEL checks. NFC.

[vkalintiris]

Summary

The only difference between the removed tests and the pre-existing
ones, is the materialization of the zero constant, which shouldn't
matter for these cases.

LGTM. Agreed, tests with a fixed zero operand are not useful in this case.

Some pre-existing labels are nit worthy though, I've highlighted them inline.

Shouldn't this be 64R6?

I know you haven't changed this, but shouldn't this be 64R6?
