Support for promoting Method* and compiler temps

This CL completes the support for allowing compiler-generated
data to be treated as a Dalvik register and become subject to
the normal register promotion and live temp tracking machinery.

Also:
   o Removes some vestigal and useless Method* loads from
     range argument setup.
   o Changes the Method* pseudo vReg number from -1 to -2 to
     avoid a conflict with the 0xffff marker in the register map.
   o Removes some experimental code for CSE at the basic block
     level.
