3cbfa1617f Add an inalloca flag to allocas 
Summary:
The only current use of this flag is to mark the alloca as dynamic, even
if its in the entry block.  The stack adjustment for the alloca can
never be folded into the prologue because the call may clear it and it
has to be allocated at the top of the stack.

087ab613f4 Correct word hyphenations 
This patch tries to avoid unrelated changes other than fixing a few
hyphen-related ambiguities and contractions in nearby lines.

db3a9e64f8 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.

1bf0ec4e16 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.

3181f5900f Respect address space sizes in isEliminableCastPair. 
This avoids constant folding bitcast/ptrtoint/inttoptr combinations
that have illegal bitcasts between differently sized address spaces.

f34dc428fa 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.

They are generally faster (at least not slower) than post-inc, post-dec.

8246df61f6 Use the AttributeSet when removing multiple attributes. Use Attribute::AttrKind 
when removing one attribute. This further encapsulates the use of the attributes.

defaca00b8 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.

0b8c9a80f2 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.

c2c50cdcdc 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)
