Allow -verify to be used with files that don't have an associated FileEntry.

In Debug builds, VerifyDiagnosticConsumer checks any files with diagnostics
to make sure we got the chance to parse them for directives (expected-warning
and friends). This check previously relied on every parsed file having a
FileEntry, which broke the cling interpreter's test suite.

This commit changes the extra debug checking to mark a file as unparsed
as soon as we see a diagnostic from that file. At the very end, any files
that are still marked as unparsed are checked for directives, and a fatal
error is emitted (as before) if we find out that there were directives we
missed. -verify directives should always live in actual parsed files, not
in PCH or AST files.

Patch by Andy Gibbs, with slight modifications by me.

[analyzer] The result of && or || is always a 1 or 0.

Forgetting to at least cast the result was giving us Loc/NonLoc problems
in SValBuilder (hitting an assertion). But the standard (both C and C++)
does actually guarantee that && and || will result in the actual values
1 and 0, typed as 'int' in C and 'bool' in C++, and we can easily model that.

[analyzer] Replace boolean IsSink parameters with 'generateSink' methods.

Generating a sink is significantly different behavior from generating a
normal node, and a simple boolean parameter can be rather opaque. Per
offline discussion with Anna, adding new generation methods is the
clearest way to communicate intent.

Code-complete 'weak' for properties under ARC-with-weak-references (or GC)

Also, suggest 'readonly' even if the property has been given an ownership
attribute ('strong', 'weak', etc). This is used when properties are declared
readonly in the public interface but readwrite in a class extension.

[analyzer] Add a test for "release and stop tracking" behavior.

This is used to handle functions and methods that consume an argument
(annotated with the ns_consumed or cf_consumed attribute), but then the
argument's retain count may be further modified in a callback. We want
to warn about over-releasing, but we can't really track the object afterwards.
