deaad8cc34 Create a new TypeNodes.def file that enumerates all of the types, 
giving them rough classifications (normal types, never-canonical
types, always-dependent types, abstract type representations) and
making it far easier to make sure that we've hit all of the cases when
decoding types. 

Switched some switch() statements on the type class over to using this
mechanism, and filtering out those things we don't care about. For
example, CodeGen should never see always-dependent or non-canonical
types, while debug info generation should never see always-dependent
types. More switch() statements on the type class need to be moved 
over to using this approach, so that we'll get warnings when we add a
new type then fail to account for it somewhere in the compiler.

As part of this, some types have been renamed:

  TypeOfExpr -> TypeOfExprType
  FunctionTypeProto -> FunctionProtoType
  FunctionTypeNoProto -> FunctionNoProtoType

There shouldn't be any functionality change...

76ba41ce4f Add Type::hasPointerRepresentation predicate. 
- For types whose native representation is a pointer.

 - Use to replace ExprConstant.cpp:HasPointerEvalType,
   CodeGenFunction::isObjCPointerType.

d7e7b8e411 first wave of fixes for @encode sema support. This is part of PR3648. 
The big difference here is that (like string literal) @encode has 
array type, not pointer type.

8eb018ab9c Support IRgen of sqrt -> llvm.sqrt, pow -> llvm.pow. 
- Define pow[lf]?, sqrt[lf]? as builtins.

 - Add -fmath-errno option which binds to LangOptions.MathErrno

 - Add new builtin flag Builtin::Context::isConstWithoutErrno for
   functions which can be marked as const if errno isn't respected for
   math functions. Sema automatically marks these functions as const
   when they are defined, if MathErrno=0.

 - IRgen uses const attribute on sqrt and pow library functions to
   decide if it can use the llvm intrinsic.

284d177c7f Wire up break and continue processing to the new stack depth adjuster. 
If people could beat on it and let me know if there are any new
semantics required by newer language standards or DRs or any little
details I goofed on, I'd be happy to fix any issues found.

0509d9635b Ensure we track all the stack depths for all break and continue points

and start code gening break and continue in the presense of vlas.
