+ added a size parameter to optimize_op_const and do a sign extension of the 'a' parameter up from the specified size, so that things like (i and $ffffffff) get optimized away the same way as (i and -1)

* MIPS: don't optimize reference twice for 64-bit loads and stores. Now loading/storing 64-bit value to global variable takes typically 3 instructions.

* MIPS: ".set macro"/".set nomacro" directives around ".cprestore" are necessary only when offset is outside smallint range. Otherwise they just clutter the assembler file.

* MIPS: set pi_do_call flag for assembler procedures with stackframes, so in PIC mode it further receives pi_needs_got in PIC mode and allocates the GP save temp.

+ MIPS: emulate "flags", i.e. support LOC_FLAGS location. This allows to generate differently optimized code for branching and for conversion to register, typically saving a register and instruction per compare.

+ 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.
