Reid Spencer 2dd0c0b27f Remove support for upgrading NOT. The llvm-upgrade lexer didn't recognize 
it either. NOT is just plain illegal now.

Anton Korobeynikov a0554d90e8 * PIC codegen for X86/Linux has been implemented 
* PIC-aware internal structures in X86 Codegen have been refactored
* Visibility (default/weak) has been added
* Docs fixes (external weak linkage, visibility, formatting)

Reid Spencer 2759b18e5d Make a couple organizational changes. Type no longer derives from Value 
(hasn't for ages) so move it up one level in the table of contents.
Type needs to be understood before Value so move it before Value. Make
the descriptions of types stand out a little more.  Add references to the
doxygen for the Type class.

Reid Spencer b9e5d10cf7 Update documentation for arbitrary precision integers: 
1. int -> i32
2. Describe the IntegerType class.
3. Correct the description of Type and its primitive type subclasses.
4. Document OpaqueType and PackedType a little better.

Reid Spencer 7a9c62baa6 For PR1064: 
Implement the arbitrary bit-width integer feature. The feature allows
integers of any bitwidth (up to 64) to be defined instead of just 1, 8,
16, 32, and 64 bit integers.

This change does several things:
1. Introduces a new Derived Type, IntegerType, to represent the number of
   bits in an integer. The Type classes SubclassData field is used to
   store the number of bits. This allows 2^23 bits in an integer type.
2. Removes the five integer Type::TypeID values for the 1, 8, 16, 32 and
   64-bit integers. These are replaced with just IntegerType which is not
   a primitive any more.
3. Adjust the rest of LLVM to account for this change.

Note that while this incremental change lays the foundation for arbitrary
bit-width integers, LLVM has not yet been converted to actually deal with
them in any significant way. Most optimization passes, for example, will
still only deal with the byte-width integer types.  Future increments
will rectify this situation.

Reid Spencer cddc9dfe97 Implement review feedback for the ConstantBool->ConstantInt merge. Chris 
recommended that getBoolValue be replaced with getZExtValue and that
get(bool) be replaced by get(const Type*, uint64_t). This implements
those changes.

Nick Lewycky ee32ee0250 If we know that it's a constant being casted, propagate through the cast 
instruction. Doesn't work the other way though (can't recover bits that

Devang Patel ad98d23f16 Start using PMStack. Now each pass is responsibe for assinging 
a pass manager for itself.
