Vasileios Kalintiris 31f9936bf5 [mips] Support SELECT nodes for targets that don't have conditional-move instructions.
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.
