gjstest v1.0.2

*   Add support for v8 4.6.

Fixed a bunch of build errors.

For the longest time I couldn't reproduce these because I couldn't begin
to build, due to the ancient and messed up version of v8 in Homebrew
(see Homebrew/legacy-homebrew#41091). As of Homebrew/legacy-homebrew@9dae089 we now
have v8 4.4.63.31 to work with, and after this commit we build and our
tests pass with the following dependencies installed by homebrew:

    gflags
    glog
    libxml2
    protobuf
    re2
    v8

Fixed some linter issues in typed_arrays_test.js.
