Bob Wilson e407736a06 Revert patches to add case-range support for PR1255. 
The work on this project was left in an unfinished and inconsistent state.
Hopefully someone will eventually get a chance to implement this feature, but
in the meantime, it is better to put things back the way the were.  I have
left support in the bitcode reader to handle the case-range bitcode format,
so that we do not lose bitcode compatibility with the llvm 3.3 release.

Matt Arsenault 065ced9bed Fix ptr vector inconsistency in CreatePointerCast 
One form would accept a vector of pointers, and the other did not.
Make both accept vectors of pointers, and add an assertion
for the number of elements.

Matt Arsenault 130e0ef6f4 Respect address space sizes in isEliminableCastPair. 
This avoids constant folding bitcast/ptrtoint/inttoptr combinations
that have illegal bitcasts between differently sized address spaces.

Matt Arsenault cacbb2377a Change behavior of calling bitcasted alias functions. 
It will now only convert the arguments / return value and call
the underlying function if the types are able to be bitcasted.
This avoids using fp<->int conversions that would occur before.

Michael Gottesman 41748d7c86 Added support for the Builtin attribute. 
The Builtin attribute is an attribute that can be placed on function call site that signal that even though a function is declared as being a builtin,

Jakub Staszak 773be0ce1f Use pre-inc, pre-dec when possible. 
They are generally faster (at least not slower) than post-inc, post-dec.

Bill Wendling 430fa9bfb3 Use the AttributeSet when removing multiple attributes. Use Attribute::AttrKind 
when removing one attribute. This further encapsulates the use of the attributes.

Bill Wendling 09175b39f2 More encapsulation work. 
Use the AttributeSet when we're talking about more than one attribute. Add a
function that adds a single attribute. No functionality change intended.

Shuxin Yang f0537ab681 Consider expression "0.0 - X" as the negation of X if 
- this expression is explicitly marked no-signed-zero, or
  - no-signed-zero of this expression can be derived from some context.

Chandler Carruth 9fb823bbd4 Move all of the header files which are involved in modelling the LLVM IR 
into their new header subdirectory: include/llvm/IR. This matches the
directory structure of lib, and begins to correct a long standing point
of file layout clutter in LLVM.

There are still more header files to move here, but I wanted to handle
them in separate commits to make tracking what files make sense at each
layer easier.

The only really questionable files here are the target intrinsic
tablegen files. But that's a battle I'd rather not fight today.

I've updated both CMake and Makefile build systems (I think, and my
tests think, but I may have missed something).

I've also re-sorted the includes throughout the project. I'll be
committing updates to Clang, DragonEgg, and Polly momentarily.

Chandler Carruth ef860a2488 Rename VMCore directory to IR. 
Aside from moving the actual files, this patch only updates the build
system and the source file comments under lib/... that are relevant.

I'll be updating other docs and other files in smaller subsequnet
commits.

While I've tried to test this, but it is entirely possible that there
will still be some build system fallout.

Also, note that I've not changed the library name itself: libLLVMCore.a
is still the library name. I'd be interested in others' opinions about
whether we should rename this as well (I think we should, just not sure
what it might break)
