There are two different versions of prototype for tcg_out_op and
tcg_out_vec_op functions:

1) using const TCGArg *args and const int *const_args arguments
2) using const TCGArg args[TCG_MAX_OP_ARGS] and const int
   const_args[TCG_MAX_OP_ARGS] aguments.

This duality causes warnings on GCC 11 and prevents build using
--enable-werror.  As second version provides more information,
unify functions prototypes to this variant.

Use the correct set of asserts during code generation.
We do not require the first input to overlap the output;
the existing interpreter already supported that.

Do not emit a uint64_t, but a tcg_target_ulong, aka uintptr_t.
This reduces the size of the constant on 32-bit hosts.
The assert for label != NULL has to be removed because that
is a valid value for exit_tb.
