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.

This reverts the following commits: 155464, 156374, 156377, 156613, 156704,

Andrea Di Biagio 377496bbad Add function attribute 'optnone'. 
This function attribute indicates that the function is not optimized
by any optimization or code generator passes with the 
exception of interprocedural optimization passes.

Tobias Grosser 0a8e12fdbb Make .bc en/decoding of AttrKind stable 
The bitcode representation attribute kinds are encoded into / decoded from
should be independent of the current set of LLVM attributes and their position
in the AttrKind enum. This patch explicitly encodes attributes to fixed bitcode
values.

With this patch applied, LLVM does not silently misread attributes written by
LLVM 3.3. We also enhance the decoding slightly such that an error message is
printed if an unknown AttrKind encoding was dected.

Bonus: Dropping bitcode attributes from AttrKind is now easy, as old AttrKinds
       do not need to be kept to support the Bitcode reader.

Benjamin Kramer 534d3a4670 Remove the Copied parameter from MemoryObject::readBytes. 
There was exactly one caller using this API right, the others were relying on
specific behavior of the default implementation. Since it's too hard to use it
right just remove it and standardize on the default behavior.

Bill Wendling 0dc08915d2 Have the bitcode writer and reader handle the new attribute references. 
The bitcode writer emits a reference to the attribute group that the object at
the given index refers to. The bitcode reader is modified to read this in and
map it back to the attribute group.

Bill Wendling ba629335de Add support in the bitcode reader to read the attribute groups. 
This reads the attribute groups. It currently doesn't do anything with them.

NOTE: In the commit to the bitcode writer, the format *may* change in the near
future. Which means that this code would also change.

Bill Wendling 56aecccee0 Initial cleanups of the param-attribute code in the bitcode reader/writer. 
Rename the PARAMATTR_CODE_ENTRY to PARAMATTR_CODE_ENTRY_OLD. It will be replaced
by another encoding. Keep around the current LLVM attribute encoder/decoder
code, but move it to the bitcode directories so that no one's tempted to use
them.

Bill Wendling 60011b8e27 Use an AttrBuilder to generate the correct AttributeSet. 
We no longer accept an encoded integer as representing all of the
attributes. Convert this via the AttrBuilder class into an AttributeSet with the
correct representation (an AttributeSetImpl that holds a list of Attribute
objects).

Bill Wendling 57625a4966 Remove some introspection functions. 
The 'getSlot' function and its ilk allow introspection into the AttributeSet
class. However, that class should be opaque. Allow access through accessor
methods instead.

Tim Northover 29178a348a Make APFloat constructor require explicit semantics. 
Previously we tried to infer it from the bit width size, with an added
IsIEEE argument for the PPC/IEEE 128-bit case, which had a default
value. This default value allowed bugs to creep in, where it was
inappropriate.

Chris Lattner ab7701749c Add a new BitstreamEntry concept, and add two helper methods for walking

Chris Lattner 59c3abc6ef BitstreamReader hasn't aged well. It's been hacked on by various people and 
has past the point of making sense.  Lets tidy things up: first step, moving
a ton of big functions out of line.

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.
