cd78e805e9 When converting a block pointer to an Objective-C pointer type, extend
the lifetime of the block by copying it to the heap, or else we'll get
a dangling reference because the code working with the non-block-typed
object will not know it needs to copy.

There is some danger here, e.g. with assigning a block literal to an
unsafe variable, but, well, it's an unsafe variable.

9320b87cff Give conversions of block pointers to ObjC pointers a different cast kind
than conversions of C pointers to ObjC pointers.  In order to ensure that
we've caught every case, add asserts to CastExpr that strictly determine
which cast kind is used for which kind of bit cast.

e9ff97b850 [analyzer] Remove the ProgramState argument from ExprEngine::evalBind; we were ignoring it anyway. No functionality change.

ee9848e20d Fix regression in -Wuninitialized involving VLAs. It turns out that we were modeling sizeof(VLAs)
incorrectly in the CFG, and also the static analyzer.  This patch regresses the analyzer a bit, but
that needs to be followed up with a better solution.

Fixes <rdar://problem/10008112>.

876e34b7b5 [analyzer] Simplify ExprEngine::VisitBinaryOperator() by removing recursive visit to subexpressions (which is no longer needed).

a9ce612fa2 Start partitioning ExprEngine.cpp into separate .cpp files that handle different parts
of the analysis (e.g., analysis of C expressions, analysis of Objective-C expressions, and so on).
