Toon Verwaest 3cad6bf5d7 Reland^2 "[runtime] Move Context::native_context to the map" 
This is a reland of c7c47c68f2.

This makes TSAN happy in addition to:

Previously I presumed that the context read from a frame in the profiler was
a valid context. Turns out that on non-intel we're not guaranteed that the
frame is properly set up. In the case we looked at, the profiler took a
sample right before writing the frame marker indicating a builtin frame,
causing the "context" pointer from that frame to be a bytecode array. Since
we'll read random garbage on the stack as a possible context pointer, I made
the code reading the native context from it a little more defensive.

Bug: v8:9860
Tbr: ulan@chromium.org, neis@chromium.org, ishell@chromium.org

Original change's description:
> [runtime] Move Context::native_context to the map
>
> Remove the native context slot from contexts by making context maps
> native-context-specific. Now we require 2 loads to go from a context to the
> native context, but we have 1 field fewer to store when creating contexts.
