bmeurer 5964152c8f [contexts] Place the initial JSArray maps on the native context directly. 
No need to have an indirection to get to the initial JSArray maps from
the native context; we only cache the fast elements maps anyway, so
those could live on the native context directly. This will also
integrate nicely with the load/store propagation in TurboFan (once we
propagate the immutable flag for FieldAccess as well).

Drive-by-fix: Also don't embed any of the initial JSArray maps in
TurboFan generated code when allocating a new JSArray, but instead
always load the appropriate map from the native context.  This way
we ensure that we never leak a reference to one of those maps and
its as efficient as embedding a constant map.

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
