Add a flag to help platform ports bootstrap V8

A "--minimal" flag turns off all optimizing compilers and activates the
interpreter. The idea is that with this flag activated, only the
platform-specific stubs and a Turbofan implementation must be complete to start
d8 and run the bulk of the tests. Note that although this flag is constructed as
a runtime flag, it must be set to true when building the snapshot and therefore
creates a compile-time dependency.

Awesome. I'd pick a different name, i.e. --bootstrap or --minimal.

LGTM.
