vanilla reverse-BFS followed by a forward-DFS instead of resulting to strange
histrionics (whose purpose I can no longer remember) in the reverse-BFS stage.
This fixes an assertion failure in BugReporter due to edge cases where no root
was being hit in the reverse-BFS phase.

clear insertion point. The rest of IRgen should theoretically take
advantage of this to avoid emitting dead code. Theory != Practice.

Always try to fold array sizes, and warn if we could fold something that isn't an ICE. This makes us compatible with GCC.

Currently this pass will delete the variable declaration info, 
and keep the line number info. But the kept line number info is not updated, 
and some is redundant or not correct, this patch just updates those info.

Add a quick pass to the stack slot colorer to eliminate some trivially redundant spills after coloring.
Ideally these would never get created in the first place, but until we enhance the spiller to have a more
global picture of what's happening, this is necessary for code quality in some circumstances.
