gcc-4.4 was optimizing away comparisons against SimpleValueType when
it was compared to a value larger than the largest value in the enum.
This patch works around it by adding one extra item to the enum so
that these tests will now be valid.

This is a Type subclass that can hold a DeclaratorInfo* when we have type source info coming
out of a declarator that we want to preserve. This is used only at the "border" of Parser/Sema for
passing/getting QualTypes, it does not participate in the type system semantics in any way.

Create and instantiate a DeclaratorInfo using a newly introduced Sema::GetDeclaratorInfoForDeclarator().

DeclaratorDecl contains a DeclaratorInfo* to keep type source info.
Subclasses of DeclaratorDecl are FieldDecl, FunctionDecl, and VarDecl.
EnumConstantDecl still inherits from ValueDecl since it has no need for DeclaratorInfo.

Decl/Sema interfaces accept a DeclaratorInfo as parameter but no DeclaratorInfo is created yet.

llvm-svn: 79392

Introduce DeclaratorInfo and TypeLoc, intended to be used for storing and reading source information for types.

DeclaratorInfo will contain a flat memory block for source information about a type that came out of a declarator.
TypeLoc and its subclasses will be used by clients as wrappers to "traverse" the memory block and read the information.

Both DeclaratorInfo and TypeLoc are not utilized in this commit.

 - Kill off begin(), end(), and iterator. It isn't clear what these
   mean. Instead provide getBufferStart(), which can be used with
   GetNumBytesInBuffer to the same effect.

 - Update ComputeColumn to take arguments for the buffer to scan, this
   simplifies the implementation of write_impl substantially.

 - This should also fix possible problems with the scanning pointer pointing
   outside of the current raw_ostream buffer.

- Drop the Candidates argument and fix all callers. Now that RegScavenger
  tracks available registers accurately, there is no need to restict the
  search.
- Make sure that no aliases of the found register are in use. This was a potential bug.

allow underlying stream classes to decline buffering. After
calling SetBuffered(), re-check whether the stream is Unbuffered
in order to handle the case where the underlying stream has
declined buffering.
