Awesome. Thanks! LGTM with one comment to address.

https://codereview.chromium.org/1309303008/diff/1/src/type-feedback-vector.cc
File src/type-feedback-vector.cc (left):

https://codereview.chromium.org/1309303008/diff/1/src/type-feedback-vector.cc...
src/type-feedback-vector.cc:5: #include "src/type-feedback-vector.h"
Please leave this include at the top as it was before. This is according to the
style guide[1] and has the purpose of ensuring that all _declarations_ needed by
src/type-feedback-vector.h are provided by that header itself (i.e. it is
self-contained). It still doesn't guarantee all _definitions_ are provided
though (which is what this CL fixes).

From the style guide[1]: "With the preferred ordering, if dir/foo.h omits any
necessary includes, the build of dir/foo.cc or dir/foo_test.cc will break. Thus,
this rule ensures that build breaks show up first for the people working on
these files, not for innocent people in other packages."
