Description Filip Pizlo 2013-03-18 01:13:23 PDT
This general mechanism ought to aid with structure watchpointing.

This is the non-buggy part of https://bugs.webkit.org/show_bug.cgi?id=112233.  It's already been reviewed, and I will roll it in separately because it is generally more useful than the specific optimizations for by-string lookups.
