big endian targets until llvm-gcc build issue has been resolved.

01542f3d80 Clean up codes in InstCombiner::SimplifyDemandedBits(): 
1. Line out nested call of APInt::zext/trunc.
2. Make more use of APInt::getHighBitsSet/getLowBitsSet.
3. Use APInt[] operator instead of expression like "APIntVal & SignBit".

97b52c260f 1. Make the APInt variable do the binary operation stuff if possible 
instead of using ConstantExpr::getXX.
2. Use constant reference to APInt if possible instead of expensive
   APInt copy.

66a82155b4 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.

baeccc8741 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).
