Speed up the AST parsing with loc/range tracking.

Summary: https://code.google.com/p/esprima/issues/detail?id=500

filterGroup was very inefficient. It was introduced to fix
https://code.google.com/p/esprima/issues/detail?id=345.
Fixing the same issue in a different (more efficient way) by inlining
the location tracking directly into parseBinaryExpression. The marker
tracking code was taken from the master branch.

The AST parsing with loc/range tracking went from 55s to 30s on a fairly
large (19MB/5000 files) JS codebase.

"npm tests" passes.
Merge branch 'harmony' of https://github.com/asukhachev/esprima into asukhachev-harmony

BONUS: synced up the versions in the source code/component.json with
package.json and fixed some lint nits.
