Add some more instruction support to optimizing compiler.
This adds a few more DEX instructions to the optimizing compiler's
builder (constants, moves, if_xx, etc).
* Changes the codegen for IF_XX instructions to use a condition
rather than comparing a value against 0.
* Fixes some instructions in the ARM disassembler.
* Fixes PushList and PopList in the thumb2 assembler.
* Switches the assembler for the optimizing compiler to thumb2
rather than ARM.
