f71698747e Fix some misc. issues with Mips16 fp stubs.
1) They should never be inlined.
2) A naming inconsistency with gcc mips16
3) Stubs should not have the global attribute

eafa96485a This is the first of three patches which creates stubs used for
Mips16/32 floating point interoperability.

When Mips16 code calls external functions that would normally have some
of its parameters or return values passed in floating point registers,
it needs (Mips32) helper functions to do this because while in Mips16 mode
there is no ability to access the floating point registers.

In Pic mode, this is done with a set of predefined functions in libc.
This case is already handled in llvm for Mips16.

In static relocation mode, for efficiency reasons, the compiler generates
stubs that the linker will use if it turns out that the external function
is a Mips32 function. (If it's Mips16, then it does not need the helper
stubs).

These stubs are identically named and the linker knows about these tricks
and will not create multiple copies and will delete them if they are not
needed.
