helper functions. This can be optimized out later when the remaining parts of the helper function work is moved into the Mips16HardFloat pass. For now it forces us to use the 32 bit save/restore instructions instead of the 16 bit ones. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187712 91177308-0d34-0410-b5e6-96231b3b80d8
