tcg: Remove unreachable code in tcg_out_op and op_defs
The INDEX_op_call case has just been obsoleted; the mov and movi
cases have not been reachable for years. Attempt to document this
both in each tcg_out_op switch, and via TCG_OPF_NOT_PRESENT.
Because of the TCG_OPF_NOT_PRESENT change, this must be done for
all targets in a single commit.
