Allow Mips16 routines to call Mips32 routines that have abi requirements that either arguments or return values are passed in floating point registers. This handles only the pic case. We have not done non pic for Mips16 yet in any form. The libm functions are Mips32, so with this addition we have a complete Mips16 hard float implementation. We still are not able to complete mix Mip16 and Mips32 with hard float. That will be the next phase which will have several steps. For Mips32 to freely call Mips16 some stub functions must be created. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@173320 91177308-0d34-0410-b5e6-96231b3b80d8
