VRP currently searches the ssa_name list for globals to exported after it

for the final time during the DOM walk.
This avoid the occasional awkwardness of determined what ssa-names in the list
are important, as well as allowing forthcoming side-effect code to adjust what
is currently known as a global value during the walk without affecting the
values exported for the entire function.
Bootstrapped on x86_64-pc-linux-gnu with no regressions. Pushed.
This (r13-436-gaf34279921f4) appears to cause or expose a problem which breaks
bootstrap with in-tree MPFR on at least x86_64-linux/darwin.
