Created Revert of Group lexical context variables for faster look up.
Description:
Revert of Group lexical context variables for faster look up. (patchset #2
id:20001 of https://codereview.chromium.org/1281883002/ )
Reason for revert:
This performance hack is no longer necessary.
Original issue's description:
Group lexical context variables for faster look up.
Currently, looking up a lexical context variable requires looking up
the variable name and then checking its mode. This can be a bottleneck
in Runtime_DeclareGlobals, even when no lexical context variables are
declared.
