VP blocks keep track of a condition, which is a VPValue. This patch
updates VPBlockBase to manage the value as a VPUser, so
replaceAllUsesWith properly updates the condition bit as well.

This is required to enable VP2VP transformations and it helps with
simplifying some of the code required to manage condition bits.
