Tom Care 9026d4b488 Adjusted the semantics of assign checking in IdempotentOperationChecker
- Fixed a regression where assigning '0' would be reported
- Changed the way self assignments are filtered to allow constant testing
- Added a test case for assign ops
- Fixed one test case where a function pointer was not considered constant
- Fixed test cases relating to 0 assignment

Tom Care 98e679508d Enabled relaxed LiveVariables analysis in the path-sensitive engine to increase the coverage of bugs. Primarily affects IdempotentOperationChecker.
- Migrated a temporarily separated test back to its original file (bug has been fixed, null-deref-ps-temp.c -> null-deref-ps.c)
- Changed SymbolManager to use relaxed LiveVariables
- Updated several test cases that the IdempotentOperationChecker class now flags
- Added test case to test relaxed LiveVariables use by the IdempotentOperationChecker

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 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.

Daniel Dunbar 8b57697954 Eliminate &&s in tests.
- 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious.

Ted Kremenek 4301526e8d Remove 'StoreManager::OldCastRegion()', TypedViewRegion (which only
OldCastRegion used), and the associated command line option
'-analyzer-store=old-basic-cast'.

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 1642bdaaa5 Introduce a new concept to the static analyzer: SValuator.
GRTransferFuncs had the conflated role of both constructing SVals (symbolic
expressions) as well as handling checker-specific logic. Now SValuator has the
role of constructing SVals from expressions and GRTransferFuncs just handles
checker-specific logic. The motivation is by separating these two concepts we
will be able to much more easily create richer constraint-generating logic
without coupling it to the main checker transfer function logic.

We now have one implementation of SValuator: SimpleSValuator.

SimpleSValuator is essentially the SVal-related logic that was in GRSimpleVals
(which is removed in this patch). This includes the logic for EvalBinOp,
EvalCast, etc. Because SValuator has a narrower role than the old
GRTransferFuncs, the interfaces are much simpler, and so is the implementation
of SimpleSValuator compared to GRSimpleVals. I also did a line-by-line review of
SVal-related logic in GRSimpleVals and cleaned it up while moving it over to
SimpleSValuator.

As a consequence of removing GRSimpleVals, there is no longer a
'-checker-simple' option. The '-checker-cfref' did everything that option did
but also ran the retain/release checker. Of course a user may not always wish to
run the retain/release checker, nor do we wish core analysis logic buried in the
checker-specific logic. The next step is to refactor the logic in CFRefCount.cpp
to separate out these pieces into the core analysis engine.

Ted Kremenek b535181199 Static Analyzer driver/options (partial) cleanup:
- Move all analyzer options logic to AnalysisConsumer.cpp.
- Unified specification of stores/constraints/output to be:
   -analyzer-output=...
   -analyzer-store=...
   -analyzer-constraints=...
  instead of -analyzer-range-constraints, -analyzer-store-basic, etc.
- Updated drivers (ccc-analyzer, scan-builds, new ccc) to obey this new
  interface
- Updated test cases to conform to new driver options
