tcg: Remove tcg_target_get_call_iarg_regs_count

The TCG targets no longer need individual implementations.

Since commit 6a18ae2d2947532d5c26439548afa0481c4529f9,
'flags' is no longer used in tcg_target_get_call_iarg_regs_count.

The remaining tcg_target_get_call_iarg_regs_count is trivial and only
called once. Therefore the patch eliminates it completely.
