Fix crash reported in <rdar://problem/6695527>. We now have

SVal::GetRValueSymbolVal do the checking if we can symbolicate a type instead of
having BasicStoreManager do it (which wasn't always doing the check
consistently). Having this check in SVal::GetRValueSymbolVal keeps the check in
one centralized place.

Fix StmtIterator bug reported in PR 3780 where a VLA within a DeclGroup would

not be consulted for its size expression when operator* was called in the

SimpleConstraintManager doesn't reason about bitwise-constraints on symbolic

Fix <rdar://problem/6611677>: Add basic transfer function support in the static
...
analyzer for array subscript expressions involving bases that are vectors. This
solution is probably a hack: it gets the lvalue of the vector instead of an
rvalue like all other types. This should be reviewed (big FIXME in
GRExprEngine).

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

The 'misc-ps.m' test case now passes with RegionStore. One case needed to be split out into 'misc-ps-basic-store.m' and 'misc-ps-region-store.m' because the behavior was different between the two store models (RegionStore flags an additional valid bug).

instead of forcing blocks on by default, make them default to off, but let

specific targets default them to on. Default blocks to on on 10.6 and later.
Add a -fblocks option that allows the user to override the target's default.
Use -fblocks in the various testcases that use blocks.
