[analyzer] After CFG has been linearized, we can have a situation where an ExpoledNode has an invalid SourceLocation (which has no correspondence in the source code). This commit is the first step to solve this problem.
 - It adds LocationContext to the PathDiagnosticLocation object and uses it to lookup the enclosing statement with a valid location.
 - So far, the LocationContext is only available when the object is constructed from the ExplodedNode.
 - Already found some subtle bugs(in plist-output-alternate.m) where the intermediate diagnostic steps were not previously shown.

llvm-dwarfdump: Make the "is debug info section" heuristic stricter so it doesn't accidentaly picks up the wrong section.

Also add some validation code to the aranges section parser.

When a back-copy is hoisted to the nearest common dominator, keep
looking up the dominator tree for a less loopy dominator, and place the
back-copy there instead.

Don't do this when a single existing back-copy dominates all the others.
Assume the client knows what he is doing, and keep the dominating
back-copy.

This prevents us from hoisting back-copies into loops in most cases.  If
a value is defined in a loop with multiple exits, we may still hoist
back-copies into that loop.  That is the speed/size tradeoff.
