  tcg: Respect highwater in tcg_out_tb_finalize

Undo the workaround at b17a6d3390f87620735f7efb03bb1c96682ff449.

If there are lots of memory operations in a TB, the slow path code
can exceed the highwater reservation.  Add a check within the loop.

  -----------
  tcg: Change ts->mem_reg to ts->mem_base

Chain the temporaries together via pointers intstead of indices.
The mem_reg value is now mem_base->reg.  This will be important later.

This does require that the frame pointer have a global temporary
allocated for it.  This is simple bar the existing reserved_regs check.

In particular, make sure the memory is memset before use.
Continues the increased use of TCGTemp pointers instead of
integer indices where appropriate.
