Maciej W. Rozycki 38bf472a15 MIPS: Add Imagination interAptiv MR2 MIPS32r3 processor support 
Add support for the Imagination interAptiv MR2 MIPS32r3 processor with
the MIPS16e2 ASE as per documentation, including in particular:

1. Support for implementation-specific interAptiv MR2 COPYW and UCOPYW
   MIPS16e2 instructions[1], for assembly and disassembly,

2. Support for implementation-specific interAptiv MR2 SAVE and RESTORE
   regular MIPS instructions[2], for assembly and disassembly,

3. ELF binary file annotation for the interAptiv MR2 MIPS architecture
   extension.

4. Support for interAptiv MR2 architecture selection for assembly, in
   the form of the `-march=interaptiv-mr2' command-line option and its
   corresponding `arch=interaptiv-mr2' setting for the `.set' and
   `.module' pseudo-ops.

5. Support for interAptiv MR2 architecture selection for disassembly,
   in the form of the `mips:interaptiv-mr2' target architecture, for
   use e.g. with the `-m' command-line option for `objdump'.

Parts of this change by Matthew Fortune and Andrew Bennett.
