[turbofan] Specialize loads of the native context.

When we specialize to the native context, we can replace loads of the
NATIVE_CONTEXT_INDEX in any known context with the appropriate native
context for that context. This allows us to constant-fold and further
optimize things like %reflect_construct, which are inserted by the
parser.

Nit: would it be really so painful to repeat the two lines from below (rather
than introduce non-trivial fall-through case)?
