MIPS JIT Patch 20091012

I svn-updated my JavaScriptCore directory and generated a new patch.

Changes in MacroAssemblerMIPS.h:
1. Added unaligned load and branch functions.
2. Fixed LUI to use (offset + 0x8000)>>16 in many places.
3. Used m_isPointer to make sure that two instructions are generated.
4. Used move() functions in all places.

Changes in MIPSAssembler.h:
1. Added lwl, lwr.
2. Fixed relocateJumps() to check pos that has 3 more instructions.

The testing showed new regressions as follows.
        ecma/Date/15.9.5.10-10.js
        ecma/Date/15.9.5.10-2.js
        ecma/Date/15.9.5.10-6.js

        ecma/Date/15.9.5.36-6.js
        ecma/Date/15.9.5.36-7.js
        ecma/Date/15.9.5.37-4.js
        ecma/Date/15.9.5.37-5.js

I need to debug it later.  Thanks!
