1064777 - Remove unnecessary CNG checks in some places

Status: RESOLVED FIXED

(Core :: JavaScript Engine, defect)

Description

[Jan de Mooij [:jandem]]

After enabling Ion/TI everywhere (bug 939562) and Ion-compiling non-CNG functions (bug 1045529), there are still some performance problems in non-CNG (chrome) code caused by (unnecessary) CNG checks in various places. I'll post some patches to remove them, so that we can hopefully close the gap between content and chrome even more.

This makes the addon in bug 911570 a lot faster.
