Fix transfer function logic in GRSimpleVals for integer casts: only support casts from integers to integers.
This fixes a crash reported by Anders Carlsson!

Added parsing/sema support for __attribute__ ((IBOutlet)), a clang-specific attribute that the static analyzer will use to recognize what ivars are IBOutlets.

scan-build is the same as the exit status of the executed build command. With
this option, the exit status of scan-build is 1 if the analyzer flagged any
bugs, and 0 otherwise.

This addresses: <rdar://problem/6075320>

Per Sam Bishop's excellent suggestion, use "system" instead of backticks to invoke sub-commands used by scan-build.  This avoids meta-character translation issues caused by a shell subprocess.

isRetain() and isRelease() now only returns true if "Retain"/"Release" appears in the suffix of a function's name.

Provide an "Analysis Scope" for Analyses so checks can either be run on code declarations (bodies) or Objective-C @implementation blocks.

clang.cpp now #include these definitions to create the command line options, and
AnalysisConsumer #includes this file to generate the switch statement to create
actions.

Renamed -check-objc-methodsigs to -warn-objc-methodsigs.

The "missing -dealloc" check is now optional: -warn-objc-missing-dealloc

Add some code to handle vector comparisons, which is the language side
of the llvm vicmp/vfcmp instructions.  Also make the vector-vector and
vector-scalar asign checks a bit more sane under the presence of lax vector
conversions.

Refactored error reporting in CheckObjCDealloc and CheckObjCInstMethSignature to use this new bug reporting interface (major code simplification).
