-Wsometimes-uninitialized. This detects cases where an explicitly-written branch
inevitably leads to an uninitialized variable use (so either the branch is dead
code or there is an uninitialized use bug).
This chunk of warnings tentatively lives within -Wuninitialized, in order to
give it more visibility to existing Clang users.

Load custom plugins when running scan-build. This is useful when
additional static analysis Checkers must be provided via clang's plugin
interface.
Loading additional plugins can now be done via the scan-build call:
scan-build -load-plugin <plugin.so>

Plus, a patch for scan-build.
* mdoc corrections
* slightly more compact output
* same license as scan-build
* DESCRIPTION describes
* Default checkers corrected & explained
* Authors credited
The patch adds support for --help-checkers. It just lists the default
checkers by recursively invoking "scan-build -h" and looking for the
magic '+' signs.

Where diagnostic about unfound property is not
issued in the context where a setter is looked up
in situation in which name and property name differ
in their first letter case. // rdar://11363363

This issue was that the source location was pointing to a
non-printable character and so CaretEnd was pointing one
_column_ past the caret but not one _character_ past the
caret. So the conversion between column and byte locations
wasn't working (because the conversion is only valid from
the first column or byte of a character).

volatile reference to a temporary is not viable. My interpretation is that
DR1152 was a bugfix, not a rule change for C++11, so this is not conditional on
the language mode. This matches g++'s behavior.

idiom that is used commonly in setters:
[backingValue autorelease];
backingValue = [newValue retain]; // in general a +1 assign

start with a cv-qualifier. DeclaratorDecl::getTypeSpecStartLoc() does not
produce the location of the first type-specifier (the cv-qualifier) in this
case, because we don't track source locations for cv-qualifiers.
No test here: I've not found a way to test this with a lit-style test, and
introducing a gtest test for this seems unwarranted. Suggestions welcome!

pointer, but such folding encounters side-effects, ignore the side-effects
rather than performing them at runtime: CodeGen generates wrong code for
__builtin_object_size in that case.
