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.

exactly one decl with a specific name in a specific context.  This
avoids a bunch of malloc traffic and shrinks StoredDeclsMap to hold
one pointer instead of 3 words (for a std::vector).

This speeds up -fsyntax-only on cocoa.h with PTH by ~7.3%.

This prevents emitting diagnostics which are almost certainly useless.

(Note that the test is checking that we emit only one diagnostic.)
