* MIPS: Fixed code generation for PIC calls to local functions. Uncovered by r32803, before that the buggy branch was never taken because all functions were global.

* TCGMIPS.a_load_reg_reg: reduce code duplication, and don't generate same register move for OS_32->OS_S32 and vice versa. Such moves explode into at least 4 instructions if register needs spilling, after which they are no longer recognized and cannot be removed by reg.allocator. So it's much better not to generate them in first place.
