tcg: Pass number of arguments to tcg_emit_op() / tcg_op_insert_*()

Browse source 
In order to have variable size allocated TCGOp, pass the number
of arguments we use (and would allocate) up to tcg_op_alloc().

This alters tcg_emit_op(), tcg_op_insert_before() and
tcg_op_insert_after() prototypes.

In tcg_op_alloc() ensure the number of arguments is in range.
