|InstrBlocks are the insn sequences generated by the insn selectors.
They are really trees of insns to facilitate fast appending, where a
left-to-right traversal yields the insns in the correct order.
|Condition codes passed up the tree.
Reg is the lower 32-bit temporary which contains the result.
Use getHiVRegFromLo to find the other VRegUnique.
Rules of this simplified insn selection game are therefore that
the returned Reg may be modified
|Holds code that references a memory address.
|Code to produce a result into a register.
If the result must go in a specific register, it comes out as Fixed.
Otherwise, the parent can decide which register to put it in.
|Change the size field in a Register.
|Grab the Reg for a CmmReg
