tcg: Remove unused opcodes
We no longer need INDEX_op_end to terminate the list, nor do we
need 5 forms of nop, since we just remove the TCGOp instead.

Backports commit 15fc7daa770764cc795158cbb525569f156f3659 from qemu

tcg: Remove opcodes instead of noping them out
With the linked list scheme we need not leave nops in the stream
that we need to process later.

tcg: Put opcodes in a linked list
The previous setup required ops and args to be completely sequential,
and was error prone when it came to both iteration and optimization.

tcg: Move some opcode generation functions out of line
Some of these functions are really quite large.  We have a number of
things that ought to be circularly dependent, but we duplicated code
to break that chain for the inlines.

This saved 25% of the code size of one of the translators I examined.

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.

tcg: Change tcg_global_mem_new_* to take a TCGv_ptr
Thus, use cpu_env as the parameter, not TCG_AREG0 directly.
Update all uses in the translators.
