Daniel Dunbar b9fd902fdc Change CGDebugInfo::setLocation to just ignore invalid locations. This
simplifies clients.

Also, add assert that RegionStack is empty when the CGDebugInfo is
destroyed.

Daniel Dunbar 23fd462f48 Add simple interface for protecting runtime functions from name
collisions.
 - Provide CodeGenModule::CreateRuntimeFunction which guarantees that
   the function it creates will have the provided name in the final
   module. This allows the runtime to have its functions protected
   from declarations of the same name in the source code.

 - One could argue that this is a reason to abuse the llvm::Module
   namespace for dealing with function redeclarations. However, that
   approach seems conceptually flawed to me. This one also happens to
   be somewhat more efficient.

No functionality change.

Daniel Dunbar aec553bfdb Prefer llvm::Function::addFnAttr(...) to F->addAttribute(~0, ...).

Devang Patel 597e70876e Now Attributes are divided in three groups
- return attributes - inreg, zext and sext
- parameter attributes
- function attributes - nounwind, readonly, readnone, noreturn

Return attributes use 0 as the index.
Function attributes use ~0U as the index.

Devang Patel 322300d1c2 Large mechanical patch.
s/ParamAttr/Attribute/g
s/PAList/AttrList/g
s/FnAttributeWithIndex/AttributeWithIndex/g
s/FnAttr/Attribute/g

This sets the stage 
- to implement function notes as function attributes and 
- to distinguish between function attributes and return value attributes.

Daniel Dunbar 7a95ca3197 Move FunctionType conversion into CGCall.cpp:
- Added CodeGenTypes::GetFunctionType, taking a CGFunctionInfo.
 - Updated Obj-C runtimes to use this instead of rolling the
   llvm::FunctionType by hand.
 - Killed CodeGenTypes::{ConvertReturnType, DecodeArgumentTypes}.

Add ABIArgInfo class to encapsulate ABI decision of how to lower types
to LLVM.
 - Will move to target sometime soon.

Daniel Dunbar c68897d2c3 Tweak CGCall functions again:
- Realized these functions will eventually need access to more data,
   moved to CodeGenModule. Eventually they should probably live
   together in some other helper class.

Daniel Dunbar 76c8eb75b1 Tweak CGCall functions:
- Move actual param attr list creation to
   CodeGenFunction::ConstructParamAttrList.
 - Make ReturnTypeUsesSret static.

Daniel Dunbar 0beedc1684 Fix a number of issues w.r.t. emission of global for functions and
aliases.
 - Attributes specific to a definition are only set when the
   definition is seen.
 - Alias generation is delayed until the end of the module; necessary
   since the alias may reference forward.
 - Fixes: PR2743, <rdr://6140807&6094512>
 - Improves: <rdr://6095112> (added XFAIL)

Also, print module on verification failures.

Daniel Dunbar 3d7c90b8ec Refactor parameter attribute handling:
- Add CGCall.h for dealing with ABI issues related to calls.
  - Add CGFunctionInfo and CGCallInfo for capturing ABI relevant
    information about functions and calls.
  - Isolate LLVM parameter attribute handling inside CGCall.cpp

Daniel Dunbar 89654eef3a Objective-C @synthesize support.
- Only supports simple assignment and atomic semantics are ignored.
 - Not quite usable yet because the methods do not actually get added
   to the class metadata.
 - Added ObjCPropertyDecl::getSetterKind (one of Assign, Copy, Retain).
 - Rearrange CodeGenFunction so synthesis can reuse function prolog /
   epilog code.

Daniel Dunbar a94ecd2a0b Add NeXT runtime support for generating methods.
Change CodeGenFunction::EmitParmDecl to take either a ParmVarDecl or an
  ImplicitParamDecl.

Drop hasAggregateLLVMType from CodeGenModule.cpp (use version in
  CodeGenFunction).

Change the Objective-C method generation to use EmitParmDecl for
  implicit parameters.

Daniel Dunbar a7c8cf6200 Change WarnUnsupported to ErrorUnsupported (in name and in practice).
- We are beyond the point where this shows up often and when it does
   generating miscompiled files is bad.

Daniel Dunbar fce4be843e Clean up CodeGenModule interface.
- Add CodeGenModule::EmitTopLevelDecl which uses switch on kind
   instead of ugly & slow dyn_cast chains.

 - Drop some simple forwarding methods into the ObjC runtime.

 - Privatize appropriate methods.

Daniel Dunbar 9299250939 Change CGObjCRuntime methods to take appropriate clang Decls.
- This is in prep for implementation class support for the NeXT
   runtime, for which the existing methods don't provide enough
   information (and additionally make too many assumptions about how
   things should be emitted).

Daniel Dunbar c4baa06d15 Add GetAddrOfConstantCString method
- Returns addr of constant for argument + '\0'.
 - I couldn't think of a better name.
 - Move appropriate users of GetAddrOfConstantString to this.

Rename getStringForStringLiteral to GetStringForStringLiteral.

Add GetAddrOfConstantStringFromLiteral
 - This combines GetAddrOfConstantString and
   GetStringForStringLiteral. This method can be, but is not yet, more
   efficient.

Change GetAddrOfConstantString to not add terminating '\0'

Daniel Dunbar 89da6ad1db Change ObjCRuntime GenerateProtocol[Ref] methods to take
ObjCProtocolDecl directly.

Implement CodeGen support for forward protocol decls (no-ops are so
    nice to implement).

Also moved CGObjCRuntime.h out of CodeGenModule.h
