Change CheckerVisitor so that [Pre,Post]VisitCallExpr only handles CallExprs for simple C functions, not
all CallExprs (including CXXMemberCallExpr, etc.).  Now the generic handler for all CallExprs is [Pre,Post]VisitGenericCallExpr.

Also add [Pre,Post]Visit hooks for CXXMemberCallExpr.

Change GRExprEngine::VisitCXXMemberCallExpr() to do pre/post checker visits of the call.

In MeasureTokenLength, the FileLoc supplied to the lexer must point to the start of the buffer, or we risk overflow.

- Use BlockEntrance rather than BlockEdge to bring in line with UnreachableCodeChecker. Fixes an issue where unreached blocks would still be counted as reachable.
- Added warnings for all BlockAborted locations. This allows us to see where the analyzer stopped analyzing.

Modified the ccc-analyzer script to print the compiler command when log level verbosity is enabled. This is handy for debugging.

Change -analyzer-max-nodes to allow 0 as a parameter. This allows the analyzer to completely analyze a worklist regardless of time taken.

Early CFG simplification can fold conditionals down to selects, which is often a good thing, but it can also
hide jump threading opportunities by turning control flow into data flow.  Run an early JumpThreading pass
(adds approximately an additional 1% to optimization time on SPEC), allowing it to get a shot at these cases
first.  Fixes <rdar://problem/8447345>.

UnreachableBlockElim could incorrectly return false when it had not modified the CFG, but HAD modified some PHI nodes.  Fixes PR8174.

Fix PR8247: JumpThreading can cause a block to become unreachable while still having predecessor, if it is part of a self-loop.
Because of this, we cannot use the Simplify* APIs, as they can assert-fail on unreachable code.  Since it's not easy to determine
if a given threading will cause a block to become unreachable, simply defer simplifying simplification to later InstCombine and/or
DCE passes.
