[PATCH] D38800: [mips] Add Triple::getABIVariant() to form a triple variant accordingly to the ABI

LLVM tools like `llc` and `llvm-mc` accept (via command line arguments) both target triple / architecture's name and ABI's name. To merge this information and form a new target triple this change introduces new `Triple` class member function `getABIVariant()`. This routine changes a target triple accordingly to the provided ABI's name. For example, accepting `mips-linux-gnu` as a target triple and `n32` as an ABI's name it forms `mips64-linux-gnuabin32`.

This patch depends on https://reviews.llvm.org/D38799.
