tcg: Compress liveness data to 16 bits
This reduces both memory usage and per-insn cacheline usage
during code generation.

tcg: Reorg TCGOp chaining
Instead of using -1 as end of chain, use 0, and link through the 0
entry as a fully circular double-linked list.

tcg: Fold life data into TCGOp
Reduce the size of other bitfields to make room.
This reduces the cache footprint of compilation.

tcg: Compress dead_temps and mem_temps into a single array
We only need two bits per temporary. Fold the two bytes into one,
and reduce the memory and cachelines required during compilation.

tcg: Lower indirect registers in a separate pass
Rather than rely on recursion during the middle of register allocation,
lower indirect registers to loads and stores off the indirect base into
plain temps.
For an x86_64 host, with sufficient registers, this results in identical
code, modulo the actual register assignments.
For an i686 host, with insufficient registers, this means that temps can
be (temporarily) spilled to the stack in order to satisfy an allocation.
This as opposed to the possibility of not being able to spill, to allocate
a register for the indirect base, in order to perform a spill.
