5e4b95b3fe 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.

76ba4f5275 Incorrect JAL instruction attributes caused the optimizer to make a wrong
instruction move. Just affects static relocation. -static works fine now
with mips16 for the most part.

1e07de3529 Add another intrinsic that LLVM gives an incorrect prototype to.
I need to go through all the runtime routine list and see if there
are any more I need to add for mips16 floating point. Prototypes must
be correct or else I don't know to add a helper function call.

25278aa26f Add the saving of S2. This is needed for some of the floating point
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.

b1fa7d4d26 Fix some issues with Mips16 floating when certain intrinsics are present.
This is actually an LLVM bug in the way it generates signatures for these
when soft float is enabled. For example, floor ends up having the signature
of int64(int64). The signature part is not the same as where the actual
parameter types are recorded, and those ARE of course int64(int64) when
soft float is enabled. (Yes, Mips16 hard float uses soft float but with
different runtime rounes but then has to interoperate with Mips32 using
normal floating point). This logic will eventually be moved to the 
Mips16HardFloat pass so it's not worth sorting out these issues in LLVM
since nobody but Mips16 cares about these signatures, as far as I know,
and even I won't eventually either.
