Jim Grosbach 40eda1076a Handle cases where the post-RA scheduler may move instructions between the 
address calculation instructions leading up to a jump table when we're trying
to convert them into a TB[H] instruction in Thumb2. This realistically
shouldn't happen much, if at all, for well formed inputs, but it's more correct
to handle it. rdar://7387682

Douglas Gregor 6df2b8c3ac Rename CXXZeroInitValueExpr to CXXScalarValueInitExpr, to reflect its 
newly-narrowed scope. No functionality change.

Douglas Gregor 442612c285 Do not use CXXZeroValueInitExpr for class types. Instead, use 
CXXConstructExpr/CXXTemporaryObjectExpr/CXXNewExpr as
appropriate. Fixes PR7556, and provides a slide codegen improvement
when copy-initializing a POD class type from a value-initialized
temporary. Previously, we weren't eliding the copy.

Chris Lattner ac5881295c Implement the major chunk of PR7195: support for 'callw' 
in the integrated assembler.  Still some discussion to be
done.

Zhanyong Wan fb617d5365 Changes how the TypeLoc traverser invokes the Type traverser: before, 
VisitFooTypeLoc() calls VisitFooType(); now, TraverseFooTypeLoc()
calls WalkUpFromFooType(). This allows clients that override
WalkUpFromFooType() to continue to work.  It also preserves the
property that Visit*() in the base visitor class is a no-op (s.t. a
subclass doesn't have to call Base::Visit*() when overriding
Visit*()).

Also fixes some typos in comments.
         
Also added a missing getDerived() inside
TraverseQualifiedTypeLoc(). The call is needed in case a subclass
overrides TraverseTypeLoc().

Howard Hinnant 189b212662 First loop test passed. The data structure and search algorithm is still crude and in-flux. But this milestone needed to be locked in. Right now every loop is implemented in terms of a structure that will handle the most complicated {min, max} loop. Though only *-loops are tested at the moment. In a future iteration *-loops will likely be optimized a little more. The only tests are for basic posix so far, but I have prototype code running for extended posix and ecma. The prototype code lacks the complicating properties of the real <regex> requirements though.

Dan Gohman ffe64b1ee5 Give FunctionLoweringInfo an MBB member, avoiding the need to pass it 
around everywhere, and also give it an InsertPt member, to enable isel

Dan Gohman 00ef93258a Remove interprocedural-basic-aa and associated code. The AliasAnalysis 
interface needs implementations to be consistent, so any code which
wants to support different semantics must use a different interface.

concept.
