[Mips] Adjust float ABI settings in case of MIPS16 mode. Hard float for mips16 means essentially to compile as soft float but to use a runtime library for soft float that is written with native mips32 floating point instructions (those runtime routines run in mips32 hard float mode). The patch reviewed by Reed Kotler. llvm-svn: 195123

Don't generate floating point stubs for mips16 code if the function is actually an instrinsic that will not occur in libc. This list here is not exhaustive but fixes the one places in test-suite where this occurs. I have filed a bug against myself to research the full list and add them to the array of such cases. In the future, actual stub generation will occur in a later phase and we won't need this code because we will know at that time during the compilation that in fact no helper function was even needed. llvm-svn: 188149

Add fabsf to the list of inlined functions; otherwise Mips16 will try and create a stub for it and this will result in a link error because that function does not exist in libc. llvm-svn: 192223
