7522c9d8e1 Don't allow MatchAddress recurse too much. This trims exponential 
behaviour in some cases.

23f7a1c947 1. Make more use of getLowBitsSet/getHighBitsSet. 
2. Use APInt[] instead of "X & SignBit".
3. Clean up some codes.
4. Make the expression like "ShiftAmt = ShiftAmtC->getZExtValue()" safe.

0b013d578d It is not possible to determine dominance between two PHI nodes 
based on their ordering. This is applicable to ETForest::dominates() also.

2777a31850 1. Make more use of getLowBitsSet/getHighBitsSet. 
2. Make the APInt value do the zext/trunc stuff instead of using
   ConstantExpr::getZExt().

2e35a58838 Replace the "implementation" keyword with "checkpoint". This more accurately 
describes its function as check against unresolved types and definitions.
This is handy for forcing error messages in assembly test cases or otherwise
ensuring that everything is resolved at that point in the assembly.

57e3f7324b Clean up codes in ComputeMaskedBits(): 
1. Line out nested use of zext/trunc.
2. Make more use of getHighBitsSet/getLowBitsSet.
3. Use APInt[] != 0 instead of "(APInt & SignBit) != 0".

07c42d43a2 GEP index sinking fixes: 
1) Take address scale into consideration. e.g. i32* -> scale 4.
2) Examine all the users of GEP.
3) Generalize to inter-block GEP's (no longer uses loopinfo).
4) Don't do xform if GEP has other variable index(es).

intermediate integer type is a bitwidth that the targets can handle.
