* Dummy implementations of a_bit_scan_reg_reg and g_stackpointer_alloc in tcg, removes the need to override these methods in every descendant code generator solely to avoid "constructing a class with abstract method" warning.

+ MIPS: implemented parameter location reusing, eliminating second copy of (potentially large) records passed by value. When parameter is passed both in registers and stack, let it have a single LOC_REFERENCE location on callee side, and store relevant registers on stack (into 16-byte area reserved by ABI) early in prologue.

* 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.
