C++'ification of Quick compiler's casts

 o Eliminate old useless LIR casts.
 o Replace remaining C-style casts with new C++ versions.
 o Unified instruction encoding enum
 o Expand usage of the auto-generated ostream helpers for enum LOG messages.
 o Replaced all usages of intptr_t with uintptr_t.
 o Fixed bug in removeRedundantBranches, and moved to common code
