<pre>Adding more branch prediction hints to the collections of `m_runtimeFlags.isAsyncAwaitEnabled() && ...` conditions seems to get a big improvement (dramatically fixing regressions in Dromaeo, and significantly mitigating the codeload regressions to less than 1% on average).
I think that's pretty good, but the branch prediction hints will not be useful forever, so more work may be needed to keep the parser performing well later.
What do you think?</pre>
