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.
