r110903 introduced a dependency from Frontend to every library that
declared an Action by introducing Action references that previously
resided in the driver in the file ExecuteCompilerInvocation.cpp.
This patch moves ExecuteCompilerInvocation to a new library named
FrontendTool which is intended to bear these dependencies.

#pragma once wasn't working on win32 if the header file was included
using a different case.
I tracked down  the problem to the fact that clang::FileManager was
caching files using case sensitive string (UniqueFiles) on Windows.

I changed FileManager to cache filename in lower case only.
Doesn't affect UNIX because UNIX uses Inode to uniquely identify files.

unix doesn't use this codepath.

ToolChain. This fixes a potenial bad cast when running Clang on PPC code, since
the tool chain in effect is not a subclass of the Darwin one, but we were
treating it like it was.
 - This introduces some gross code duplication, but the right fix for it is to
   just move the Driver to start depending on the targets in libBasic, so I am
   not planning on fixing it immediately.

constructors. We perform semantic checking when creating the definition, and
this isn't needed in certain contexts (value initialization) but is in others
(default initialization). This fixes PR7948.

We add explicit code to the default initialization path to ensure the
definition is both present and valid.

Doug, please review. I think this follows your latest suggestion, and it ended
up remarkably cleaner than I anticipated. Also let me know if similar logic
should be followed for destructors and copy-constructors.

That revision started classifying truly empty structs like "Y" and "X"
as being NoClass/NoClass and turning them into 'ignore'.  The call code
turns around and allocates space for the ignored argument with 
GetUndefRValue.  The bug is that GetUndefRValue would return the address
as undef, instead of returning an object with a defined address but 
undefined contents.

Make CGT defer to the ABI on all member pointer types.
This requires giving CGT a handle to the ABI.
It's way easier to make that work if we avoid lazily creating the ABI.
Make it so.
