Initial commit of a new testsuite feature: test categories.
This feature allows us to group test cases into logical groups (categories), and to only run a subset of test cases based on these categories.
Each test-case can have a new method getCategories(self): which returns a list of strings that are the categories to which the test case belongs.
If a test-case does not provide its own categories, we will look for categories in the class that contains the test case.
If that fails too, the default implementation looks for a .category file, which contains a comma separated list of strings.
The test suite will recurse look for .categories up until the top level directory (which we guarantee will have an empty .category file).
The driver dotest.py has a new --category <foo> option, which can be repeated, and specifies which categories of tests you want to run.
(example: ./dotest.py --category objc --category expression)
All tests that do not belong to any specified category will be skipped. Other filtering options still exist and should not interfere with category filtering.
A few tests have been categorized. Feel free to categorize others, and to suggest new categories that we could want to use.
All categories need to be validly defined in dotest.py, or the test suite will refuse to run when you use them as arguments to --category.
In the end, failures will be reported on a per-category basis, as well as in the usual format.
This is the very first stage of this feature. Feel free to chime in with ideas for improvements!

ARM: Use a dedicated intrinsic for vector bitwise select.
The expression based expansion too often results in IR level optimizations
splitting the intermediate values into separate basic blocks, preventing
the formation of the VBSL instruction as the code author intended. In
particular, LICM would often hoist part of the computation out of a loop.

Implement faux-body-synthesis of well-known functions in the static analyzer when
their implementations are unavailable. Start by simulating dispatch_sync().
This change is largely a bunch of plumbing around something very simple. We
use AnalysisDeclContext to conjure up a fake function body (using the
current ASTContext) when one does not exist. This is controlled
under the analyzer-config option "faux-bodies", which is off by default.
The plumbing in this patch is largely to pass the necessary machinery
around. CallEvent needs the AnalysisDeclContextManager to get
the function definition, as one may get conjured up lazily.
BugReporter and PathDiagnosticLocation needed to be relaxed to handle
invalid locations, as the conjured body has no real source locations.
We do some primitive recovery in diagnostic generation to generate
some reasonable locations (for arrows and events), but it can be
improved.

Fixed a problem where persistent variables did
not correctly store the contents of Objective-C
classes. This was due to a combination of
factors:
1) Types were only being completed if we were
looking inside them for specific ivars
(using FindExternalVisibleDeclsByName).
We now look the complete type up at every
FindExternalLexicalDecls.
2) Even if the types were completed properly,
ValueObjectConstResult overrode the type
of every ValueObject using the complete type
for its class from the debug information.
Superclasses of complete classes are not
guaranteed to be complete. Although "frame
variable" uses the debug information,
the expression parser does now piece together
complete types at every level (as described
in Bullet 1), so I provided a way for the
expression parser to prevent overriding.
3) Type sizes were being miscomputed by
ClangASTContext. It ignored the ISA pointer
and only counted fields. We now correctly
count the ISA in the size of an object.
