[PATCH] [compiler-rt][builtins][MIPS] Add test-cases for mips16 wrappers for float arithmetic, comparison & conversion

[Faraz Shahbazker]

sgundapa remarked that he was working on a lit configuration for builtins, [[ http://reviews.llvm.org/D4251 | here ]]. It would be nice to have the framework at hand, but strictly speaking that is a parallel activity to the addition of unit tests.

By the way, the feature implementation for these tests is also still [[ http://reviews.llvm.org/D4454 | under review ]].
