Bob Wilson 8e5acc5cc1 Use the new Triple::getMacOSXVersion function in another place.
I removed support for "*-darwin*-iphoneos" triples, since we now have
iOS listed as a separate OS in the triples.

Ted Kremenek 73665188fc Really remove FlatStoreManager and BasicStoreManager, this time from the driver. Also remove associated tests. Sorry for the messy commits; this is the result of a botched Git merge.

Zhongxing Xu 685a1d818d Refactor the AnalysisConsumer to analyze functions after the whole
translation unit is parsed. This enables us to inline some calls when still
analyzing one function at a time.

Actions are classified into Function, CXXMethod, ObjCMethod, 
ObjCImplementation.

This does not hurt performance much. The analysis time for sqlite3.c:

before:
real    17m52.440s
user    17m49.460s
sys    0m2.010s

after:
real    18m0.500s
user    17m56.900s
sys    0m2.330s

DisplayProgress option is broken now. -inine-call action is removed. It
will be reenabled in another form, perhaps as an indenpendant option.

Chris Lattner 198cb4df6e Instead of counting totally diagnostics, split the count into a count
of errors and warnings.  This allows us to emit something like this:

2 warnings and 1 error generated.

instead of:

3 diagnostics generated.

This also stops counting 'notes' because they are just follow-on information
about the previous diag, not a diagnostic in themselves.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Ted Kremenek 1fc1f20efd For the nil-receiver checker, take into account the behavioral changes that got introduced in Mac OS X 10.5 and later, notably return values of double, float, etc., will not be garbage. Fixes <rdar://problem/6829160>.

Ted Kremenek 005e8a06f2 Cleanups and fixes to the nil-receiver checker, some of it fallout the
initial transition of the nil-receiver checker to the Checker
interface as done in r89745.  Some important changes include:

1) We consolidate the BugType object used for nil receiver bug
reports, and don't include the type of the returned value in the
BugType (which would be wrong if a nil receiver bug was reported more
than once)

2) Added a new (temporary) flag to CheckerContext: DoneEvauating.
This is used by GRExprEngine when evaluating message expressions to
not continue evaluating the message expression if this flag is set.
This flag is currently set by the nil receiver checker.  This is an
intermediate solution to allow the nil-receiver checker to properly
work as a plug-in outside of GRExprEngine.  Basically, this flag
indicates that the entire message expression has been evaluated, not
just a precondition (which is what the nil-receiver checker does).
This flag *should not* be repurposed for general use, but just to pull
more things out of GRExprEngine that already in there as we devise a
better interface in the Checker class.

3) Cleaned up the logic in the nil-receiver checker, making the
control-flow a lot easier to read.

Ted Kremenek 4ef13f8ac9 Add clang-cc option "--analyzer-experimental-internal-checks". This
option enables new "internal" checks that will eventually be turned on
by default but still require broader testing.

Ted Kremenek f66557978e Switch BasicStoreManager to use the new CastRegion implementation by default,
and replace the 'clang-cc' option '-analyzer-store=basic-new-cast' with
'-analyzer-store=basic-old-cast'. We'll keep the old CastRegion implementation
around for a little while for regression testing.

Ted Kremenek 605fee8445 New static analyzer check by Nikita Zhuk!
"The attached patch generates warnings of cases where an ObjC message is sent to
a nil object and the size of return type of that message is larger than the size
of void pointer. This may result in undefined return values as described in PR
2718.  The patch also includes test cases."
