Comment (by gk):

 Replying to [comment:5 gk]:
 > Why should we remove `javascript.options.typeinference`? Looking at JIT
 code it seems still to be there.
 > Updating the tooltip and removing "asm.js" and adding "native_regexp"
 seems to be a good idea.

 I stand corrected. I am not sure anymore why I thought we still have this
 pref available. Looking again convinces me that it is indeed gone. Arthur
 pointed me to https://bugzilla.mozilla.org/show_bug.cgi?id=972817 which
 puts additional weight on the "is-gone-theory". I'll update the patch
 accordingly.
