 Fix compilation error with GCC 12

 This hits a bug in unreleased GCC 12 snapshots, due to an ambiguous
std::pair constructor. It can be easily avoided and improve the code at
the same time, by using nullptr for the pointer, and using emplace to
avoid an unnecessary temporary.

 Fixed problem with resolved values caching in JointMatrix resolution…

… pass.

This patch fixes problem with JointMatrix value caching that caused
wrong value to be fetch from the cache. This patch also optimizes PHI
node resolution by removing the need to resolve first incoming value
before creating a new PHI node. With this change in place the
placeholding mechanism is no longer needed.
