Summary:
These ISA's didn't add any instructions so they are almost identical to
Mips32r2 and Mips64r2. Even the ELF e_flags are the same, However the ISA
revision in .MIPS.abiflags is 3 or 5 respectively instead of 2.

Summary:
This commit enables the MIPS-III target and adds support for code
generation of SELECT nodes. We have to use pseudo-instructions with
custom inserters for these nodes as MIPS-III CPUs do not have
conditional-move instructions.
Depends on D6212

Summary:
For Mips targets that do not have conditional-move instructions, ie. targets
before MIPS32 and MIPS-IV, we have to insert a diamond control-flow
pattern in order to support SELECT nodes. In order to do that, we add
pseudo-instructions with a custom inserter that emits the necessary
control-flow that selects the correct value.
With this patch we add complete support for code generation of Mips-II targets
based on the LLVM test-suite.
