MIPS/BFD: Don't stop processing on `bfd_reloc_outofrange'

Upon a `bfd_reloc_outofrange' error continue processing so that any
further issues are also reported, similarly to how `bfd_reloc_overflow'
is handled.  Adjust message formatting accordingly, using `%X' to abort
processing at conclusion.

Reduce the number of test cases by grouping relocations the handling of
which can now be verified together with a single source and dump.
