  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.

  Log Message:
  -----------
  tcg: Reduce ifdefs in tcg-op.c

Almost completely eliminates the ifdefs in this file, improving
confidence in the lesser used 32-bit builds.

  tcg: Introduce tcg_op_buf_count and tcg_op_buf_full

The method by which we count the number of ops emitted
is going to change.  Abstract that away into some inlines.

  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.

With the linked list scheme we need not leave nops in the stream
that we need to process later.

Rather reserving space in the op stream for optimization,
let the optimizer add ops as necessary.

  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.
