MIPS/GAS/testsuite: Fix JALR relocation tests for IRIX targets

With IRIX targets the JALR hint relocation is not produced for the o32
ABI, where it is considered a GNU extension.  Consequently several tests
fail as the output produced by GAS fails to match patterns expecting the
relocation to be present where appropriate, even though output produced
is indeed correct.

As the absence of the relocation is expected, fix the tests by providing
respective alternative dump patterns with any JALR relocations removed,
removing numerous failures with `*-*-irix*' targets:

Strictly speaking no MIPSr6 or microMIPS target is supported by IRIX,
but GAS supports such configurations on the basis of uniformity, so
provide the relevant patterns too rather than excluding the combinations
from testing.
