Revert "Upgrade V8 to 3.7.1"

This reverts commit 92f5a5d3caf01f382f90c235e9057590a5e76870.

V8 3.7.1 in debug mode on ia32 has a curious race-like bug where an fs.Stats
object is not fully formed until some time after it's created. This is easy
to demonstrate by running `make test-debug`.

V8 3.7.0 does not exhibit this behaviour so back we go.

Fixes #1981.
