Fixed static analyzer concern about null value
dereference. getStmtForDiagnostics() can return
null. Ensure statement exists before dereference
in PathDiagnosticLocation::createBegin().

I'm involved with the Static Analyzer for the most part.
I think we should embrace newer language standard features and gradually
move forward.

Thanks @kazu for helping me clean these parts in D127799.
I'm leaving the dump methods, along with the unused visitor handlers and
the forwarding methods.
The dead parts actually helped to uncover two bugs, to which I'm going
to post separate patches.

This avoids an unnecessary copy required by 'return OS.str()', allowing
instead for NRVO or implicit move. The .str() call (which flushes the
stream) is no longer required since 65b13610a5226b84889b923bae884ba395ad084d,
which made raw_string_ostream unbuffered by default.

Certain Fuchsia functions may return handles that are not owned by the
current closure. This adds a check in order to determine when these
handles are released.

When we annotating a function header so that it could be used by other
TU, we also need to make sure the function is parsed correctly within
the same TU. So if we can find the function's implementation,
ignore the annotations, otherwise, false positive would occur.
Move the escape by value case to post call and do not escape the handle
if the function is inlined and we have analyzed the handle.

Support adding handle annotations to sturucture that contains
handles. All the handles referenced by the structure (direct
value or ptr) would be treated as containing the
release/use/acquire annotations directly.

`OS << ND->getDeclName();` is equivalent to `OS << ND->getNameAsString();`
without the extra temporary string.
This is not quite a NFC since two uses of `getNameAsString` in a
diagnostic are replaced, which results in the named entity being
quoted with additional "'"s (ie: 'var' instead of var).
Some checkers may not only depend on language options but also analyzer options.
To make this possible this patch changes the parameter of the shouldRegister*
function to CheckerManager to be able to query the analyzer options when
deciding whether the checker should be registered.

Lambdas creating path notes using NoteTags still take BugReport as their
parameter. Since path notes obviously only appear in PathSensitiveBugReports
it is straightforward that lambdas of NoteTags take PathSensitiveBugReport
as their parameter.
