  -----------
  Implemented IP patch application for ARM.

Updated IPPatch::apply for ARM. Most of the complexity required on Power is avoided here since we have an instruction available (ADR) to get the current PC.
Also updated moveValueToReg in insnCodeGen to accept a vector of registers to be excluded when getting a scratch register.
