Argyrios Kyrtzidis 7910d7b72a Make changes to SDiagsWriter to make it work in combination with the ARC migrator: 
-Allow it to be used with multiple BeginSourceFile/EndSourceFile calls; for this introduce
 a "finish" callback method in the DiagnosticConsumer. SDiagsWriter finishes up the serialization
 file inside this method.
-Make it independent of any particular DiagnosticsEngine; make it use the SourceManager of the
 Diagnostic object.
-Ignore null source ranges.

Jakob Stoklund Olesen 2f0400b780 Eliminate delta argument from AdjustBBOffsetsAfter. 
The block offset can be computed from the previous block. That is more
robust than keeping track of a delta.

Eliminate one redundant AdjustBBOffsetsAfter call.

Douglas Gregor e7ab36693b Implement basic support for private headers in frameworks. In essence, 
when we load a module map (module.map) from a directory, also load a
private module map (module_private.map) for that directory, if
present. That private module map can inject a new submodule that
captures private headers.

Richard Smith 42d3af9d95 When folding the size of a global scope VLA to a constant, require the array 
bound to not have side effects(!). Add constant-folding support for expressions
of void type, to ensure that we can still fold ((void)0, 1) as an array bound.

Jim Grosbach ba39592cee Extend AsmMatcher token literal matching to allow aliasing. 
For example, ARM allows:
    vmov.u32 s4, #0  -> vmov.i32, #0
'u32' is a more specific designator for the 32-bit integer type specifier
and is legal for any instruction which accepts 'i32' as a datatype suffix.

We want to say,
    def : TokenAlias<".u32", ".i32">;

This works by marking the match class of 'From' as a subclass of the
match class of 'To'.

Richard Smith 1e1f5abf77 DeadStoresChecker: when whitelisting dead initializations with constants, look 
for a foldable constant rather than an IR-level constant. This is still far too
liberal, but is a step in the right direction.

Anna Zaks c25efccc8b [analyzer] Propagate taint through NonLoc to NonLoc casts. 
- Created a new SymExpr type - SymbolCast.
 - SymbolCast is created when we don't know how to simplify a NonLoc to
NonLoc casts.
 - A bit of code refactoring: introduced dispatchCast to have better
code reuse, remove a goto.
 - Updated the test case to showcase the new taint flow.

Richard Smith 161f09abd7 Move vector bitcast handling in constant expressions from the expression 
evaluator into constant initializer handling / IRGen. The practical consequence
of this is that the bitcast now lives in the constant's definition, rather than
in its uses.

The code in the constant expression evaluator was producing vectors of the wrong
type and size (and possibly of the wrong value for a big-endian int-to-vector
bitcast). We were getting away with this only because we don't yet support
constant-folding of any expressions which inspect vector values.
