tcg: exclude non-memory effecting helpers from instrumentation
There are actually a whole bunch of helpers that don't affect memory that we shouldn't instrument. They are helpfully identified by the TCG_CALL_NO_SIDE_EFFECTS flag which marks out lookup_tb_ptr as well as a lot of the maths helpers. To avoid the string compare we introduce a new flag for plugin internals so we skip that too.
