Mike Stump 3bc0a3bf7d One second thought, I think I want to limit this class to just vtable 
building activities.

Mike Stump 78696a70bf Implement more of the inductive case for vtable layout involving 
virtual base primaries and improve the layout of classes with virtual
bases.  WIP.

Hey, I've decided I want a change to FileCheck, I need to ensure that
the group is together, nothing in between.  Can we change it to check
the match line is from the line immediately following the last matched
line, if the source for the matched line is immediately after the
source for the previously matched line?

// CHECK: 1
// CHECK: 2
// CHECK: 3

// CHECK: 4
// CHECK: 5
// CHECK: 6

would require 1 2 and 3 to be continuous in the output, and 4 5 and 6
to be continuous.

Ted Kremenek c23c7e6a51 Change uses of: 
Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsRecordType() -> Type::getAs<RecordType>()
  Type::getAsPointerType() -> Type::getAs<PointerType>()
  Type::getAsBlockPointerType() -> Type::getAs<BlockPointerType>()
  Type::getAsLValueReferenceType() -> Type::getAs<LValueReferenceType>()
  Type::getAsRValueReferenceType() -> Type::getAs<RValueReferenceType>()
  Type::getAsMemberPointerType() -> Type::getAs<MemberPointerType>()
  Type::getAsReferenceType() -> Type::getAs<ReferenceType>()
  Type::getAsTagType() -> Type::getAs<TagType>()
  
And remove Type::getAsReferenceType(), etc.

This change is similar to one I made a couple weeks ago, but that was partly
reverted pending some additional design discussion. With Doug's pending smart
pointer changes for Types, it seemed natural to take this approach.

Ted Kremenek 8a286fbdb9 Per offline discussion with Steve Naroff, add back Type::getAsXXXType() methods 
until Doug Gregor's Type smart pointer code lands (or more discussion occurs).
These methods just call the new Type::getAs<XXX> methods, so we still have
reduced implementation redundancy. Having explicit getAsXXXType() methods makes
it easier to set breakpoints in the debugger.

Chris Lattner e0be0dfced push GlobalDecl through enough of the CodeGenModule interfaces 
to allow us to support generation of deferred ctors/dtors.
It looks like codegen isn't emitting a call to the dtor in 
member-functions.cpp:test2, but when it does, its body should
get emitted.

Anders Carlsson b7f8f594f3 Implement basic code generation of constructor calls. We can now compile: 
struct S {
S(int, int);
};

void f() {
S s(10, 10);
}

Daniel Dunbar 22a87f94a9 Pull COdeGenFunction::CreateStaticBlockVarDecl (just for creating the 
global variable) out of GenerateStaticBlockVarDecl. 
 - No intended functionality change.
 - Prep for some mild cleanups and PR3662.

Douglas Gregor ffca3a21f1 Provide a new kind of iterator, the specific_decl_iterator, that 
filters the decls seen by decl_iterator with two criteria: the dynamic
type of the declaration and a run-time predicate described by a member
function. This simplifies EnumDecl, RecordDecl, and ObjCContainerDecl
considerably. It has no measurable performance impact.

Eli Friedman c8a590dda3 Warning fixes to operator precedence warnings. 
Someone should double-check that I didn't somehow break ObjC 
serialization; I think the change there actually changes the semantics.

Chris Lattner e4b95698df Rename Selector::getName() to Selector::getAsString(), and add 
a new NamedDecl::getAsString() method.

Change uses of Selector::getName() to just pass in a Selector 
where possible (e.g. to diagnostics) instead of going through
an std::string.

This also adds new formatters for objcinstance and objcclass
as described in the dox.
