Allow v8 to allocate more heap (aws#1336)

Prevent out-of-memory errors encountered during `lerna bootstrap` on
certain systems by allowing Node's v8 engine to allocate more heap.  The
default, even on 64-bit architectures, is too small (1.4GB) to
complete compilation successfully, so we set it to 4GB for the bootstrap
phase.
