We're about to split out bytecode output into helpers, but
we can't do that one at a time if tcg_out_op_t is being done
outside of the switch.

Actually print arguments as opposed to simply the opcodes
and, uselessly, the argument counts. Reuse all of the helpers
developed as part of the interpreter.

This function is unused. It's not even the disassembler,
which is print_insn_tci, located in disas/tci.c.

This performs the size check while reading the arguments,
which means that we don't have to arrange for it to be
done after the operation. Which tidies all of the branches.

We are currently using the "natural" size routine, which
uses 64-bits on a 64-bit host. The TCGMemOpIdx operand
has 11 bits, so we can safely reduce to 32-bits.

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.
Split out tci_args_rrrbb in the translator.
Use the deposit32/64 functions rather than inline expansion.

Convert to indirect jumps, as it's less complicated.
Then we just have a pointer to the tb address at which
the chain is stored, from which we read.

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.

Begin splitting out functions that do pure argument decode,
without actually loading values from the register set.
This means that decoding need not concern itself between
input and output registers. We can assert that the register
number is in range during decode, so that it is safe to
simply dereference from regs[] later.

In the next patches, we want to use tci_read_r to return
the raw register number. So rename the existing function,
which returns the register value, to tci_read_rval.
