An algorithm for incrementally updating LoopInfo within a
LoopPassManager. The incremental update should be extremely cheap in
most cases and can be used in places where it's not feasible to
regenerate the entire loop forest.

- "Unloop" is a node in the loop tree whose last backedge has been removed.
- Perform reverse dataflow on the block inside Unloop to propagate the
  nearest loop from the block's successors.
- For reducible CFG, each block in unloop is visited exactly
  once. This is because unloop no longer has a backedge and blocks
  within subloops don't change parents.
- Immediate subloops are summarized by the nearest loop reachable from
  their exits or exits within nested subloops.
- At completion the unloop blocks each have a new parent loop, and
  each immediate subloop has a new parent.

Analyzer Core: In checkDeadSymbols checker callback, provide the state in which the symbols are not yet deleted so that checkers could inspect them. Since we are now always creating a transition in ProcessStmt(), remove the logic for adding a transition when none was generated. TODO: the extra transitions will have to be removed; more cleanups; a checker that tests teh new fucntionality.

10 second timeout zone. When launching we increase the
timeout to 10 seconds to ensure we have time to launch a
process, and then set it back.

a member template, e.g.,

  x.f<int>

if we have found a template in the type of x, but the lookup in the
current scope is ambiguous, just ignore the lookup in the current
scope.  Fixes <rdar://problem/9915664>.

While extending definition range of a debug variable, consult lexical scopes also. There is no point extending debug variable out side its lexical block. This provides 6x compile time speedup in some cases.

problem in which empty string literals were not
being compiled correctly ((int)printf("") would
print garbage).

Added a testcase that covers both.

we prevent the need to save multiple scalars to memory, making a single regular
store.
