CodeGen: When emitting stores for an initializer, only emit a GEP if we really need the store.

This avoids emitting many dead GEPs for large zero-initialized arrays.

[libclang] When determining the cursor via a location, ignore synthesized ivars otherwise
if we have something like:

   @synthesize prop = _prop;

and '_prop' is not declared, we will encounter a '_prop' ivar before
encountering the 'prop' synthesize declaration and we will think that
we passed the region-of-interest, missing the cursor for 'prop'.

[ms-inline asm] Hoist more common code into the AsmStmt base class.  Add stubs
with FIXMEs for unimplemented features.  No functional change intended.

[analyzer] Rename CallEvent::mayBeInlined to CallEvent::isCallStmt.

The two callers are using this in order to be conservative, so let's just
clarify the information that's actually being provided here. This is not
related to inlining decisions in any way.

No functionality change.

[analyzer] If the last store into a region came from a function, step into it.

Previously, if we were tracking stores to a variable 'x', and came across this:

x = foo();

...we would simply emit a note here and stop. Now, we'll step into 'foo' and
continue tracking the returned value from there.

[analyzer] Refactor FindLastStoreBRVisitor to not find the store ahead of time.

As Anna pointed out to me offline, it's a little silly to walk backwards through
the graph to find the store site when BugReporter will do the exact same walk
as part of path diagnostic generation.

[analyzer] Rename addTrackNullOrUndefValueVisitor to trackNullOrUndefValue.

This helper function (in the clang::ento::bugreporter namespace) may add more
than one visitor, but conceptually it's tracking a single use of a null or
undefined value and should do so as best it can.

Also, the BugReport parameter has been made a reference to underscore that
it is non-optional.

Warn about suspicious implicit conversions from floating point to bool

This warns in two specific situations:

1) For potentially swapped function arguments, e.g.

     void foo(bool, float);
     foo(1.7, false);

2) Misplaced brackets around function call arguments, e.g.

     bool InRange = fabs(a - b < delta);

   Where the last argument in a function call is implicitly converted
   from bool to float, and the function returns a float which gets
   implicitly converted to bool.

Patch by Andreas Eckleder!
