Split the pattern parsing code out from the dag isel emitter into it's own file.

Change the PointerType api for creating pointer types. The old functionality of PointerType::get() has become PointerType::getUnqual(), which returns a pointer in the generic address space. The new prototype of PointerType::get() requires both a type and an address space.

throw exceptions", just mark intrinsics with the nounwind
attribute.  Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

Add TGParser files to VStudio project files.  Removed generated files section from TableGen project file as it is no longer needed.  #Include <algorithm> directly from TGParser.cpp so it can see std::reverse.

This makes the parser much easier to understand, eliminates a ton of global variables,
and gives tblgen nice caret diagnostics.  It is also faster, but tblgen probably doesn't
care about performance.

There are a couple of FIXMEs which I will take care of next.

I added the lexing files to the VStudio projects and removed the .l files from the 
VStudio projects.  There was a problem with use of strtoll in TGLexer.cpp and Chris
suggested switching to strtol, so that's included here.

Additionally, this checkin adds minimal x64 builds to the VStudio builds.  Build issues
related to x64 in the windows specific files for DynamicLibrary.inc and Singals.inc
are worked around, but not ultimately solved.  Binaries used to be stored in

...\win32\{Debug|Release}

but are now kept in

...\win32\bin\{win32|x64}\{Debug|Release}

intermediate files will continue to be stored in the individual project directories under 
win32.  

Some names will likely change in the future to reflect that the vstudio projects
are no longer 32-bit only, but I wanted to get things up and running today so kept away
from bigger restructuring.

in favour of teaching CCAssignToStack that size 0 and/or align
0 means to use the ABI values.  This seems a neater solution.
It is safe since no legal value type has size 0.

This makes DwarfRegNum to accept list of numbers instead.
Added three different "flavours", but only slightly tested on x86-32/linux.
Please check another subtargets if possible,

Silenced some VC warnings.

I'm getting linker errors, though: unresolved externals:

llvm::Split<class llvm::BasicBlock *,struct llvm::GraphTraits<class llvm::BasicBlock *> >(class llvm::DominatorTreeBase<class llvm::BasicBlock> &,class llvm::BasicBlock *)

and

llvm::Split<struct llvm::Inverse<class llvm::BasicBlock *>,struct llvm::GraphTraits<struct llvm::Inverse<class llvm::BasicBlock *> > >(class llvm::DominatorTreeBase<class llvm::BasicBlock> &,class llvm::BasicBlock *)

Where are these defined?
