510a6b249c be more aggressive about transforming add -> or when the operands have no 
intersecting bits.  This triggers all over the place, for example in lencode,
with adds of stuff like:

	%tmp580 = mul i32 %tmp579, 2	
	%tmp582 = and i32 %b8, 1
and

	%tmp28 = shl i32 %abs.i, 1		
	%sign.0 = select i1 %tmp23, i32 1, i32 0
and
	%tmp344 = shl i32 %tmp343, 2	
	%tmp346 = and i32 %tmp96, 3

etc.

1c11cba7ec Check that always_inline functions are inlined 
whether or not -funit-at-a-time is used (C++ uses
it, C doesn't) - it was working before only when
not doing unit-at-a-time.

568cd9c076 On Darwin, the string header file isn't 64-bit clean. The use of 
"-Wshorten-64-to-32 -Werror" will cause a failure when compiling this complex
program:

#include <string>

class Path {
  mutable std::string path;
public:
  bool operator == (const Path &that) {
    return path == that.path;
  }
};

Using strcmp gets us past this annoying error.

3e607df2f8 Fix this test. It was testing broken behavior in that it required ADCE to eliminate 
a potentially infinite loop, which is undesirable.  Instead, test the LICM behavior
that we're really interested in.

fe7f6bc9ce Revert the change from r51157 in 
test/Verifier/2002-11-05-GetelementptrPointers.ll, which was incorrect.
Instead, fix getIndexedType to not follow pointer types, as
PointerType is a subclass of CompositeType.

2da4145cd8 Fix a bug in LoopStrengthReduce that caused it to emit IR with 
use-before-def. The problem comes up in code with multiple PHIs where
one PHI is being rewritten in terms of the other, but the other needs
to be casted first. LLVM rules requre the cast instruction to be
inserted after any PHI instructions, but when instructions were
inserted to replace the second PHI value with a function of the first,
they were ended up going before the cast instruction. Avoid this
problem by remembering the location of the cast instruction, when one
is needed, and inserting the expansion of the new value after it.

This fixes a bug that surfaced in 255.vortex on x86-64 when
instcombine was removed from the middle of the loop optimization
passes.
