Artem Dergachev be07303569 [analyzer] Self-debug: Dump environment frame-by-frame. 
It makes it easier to discriminate between values of similar expressions
in different stack frames.

It also makes the separate backtrace section in ExplodedGraph dumps redundant.

Artem Dergachev 30ed5467a4 [analyzer] Minor fixes and improvements to debug.ExprInspection 
- Fix the bug with transition handling in ExprInspectionChecker's
  checkDeadSymbols implementation.

- Test this bug by adding a new function clang_analyzer_numTimesReached() to
  catch number of passes through the code, which should be handy for testing
  against unintended state splits.

- Add two more functions should help debugging issues quickly without running
  the debugger or dumping exploded graphs - clang_analyzer_dump() which dump()s
  an SVal argument to a warning message, and clang_analyzer_printState(), which
  dump()s the current program state to stderr.
