This is the first patch in the series to make SCCVN able to remove
redundant comparisons by recording conditionals being true on
visited edges. This part of the series fully transitions the
toplevel walk gathering entries to SCCs we value-number to the
DOM walk which at the moment only visits las

This brings FRE/PRE up to the same level as DOM in being able to
remove redundant conditionals. It does so by inserting temporary
conditional expressions proved to be true on single predecessor
edges.
I've had to do a lot of testcase adjustments, thus the patch is
now re-bootstrapping / testing

I've committed this patch to
a) fix the breakage I caused this morning, sorry
b) Add a ptx-specific implementation of the fork_join hook. We only need to
keep worker & vector-level forks & joins, and then only when the dimension size

Hi,
The attached patch is a revision of the functionality required to
handle the declare directive. The motivation for the change was that
the original code was deemed to fragile and difficult to maintain.
The new code is now smaller, in terms of line count, and hopefully,
easier to understand.
