Wojciech Matyjewicz 86d51b896e Make these loops follow GetGEPOperands() behavior. 
Let: %q = GEP %p, X, ...
If %p is a GEP, we can chase baseptr further, only if X==0.

Owen Anderson 1f93edd08a Remove ugly and horrible code. It's not necessary for correctness, and can be added back later if it causes code quality issues.

Zhou Sheng 461d8419a7 Remove this testcase as it will always fail on 
platform like Darwin.

Duncan Sands fde556745b Remove host endianness info from TargetData and 
put it in a new header System/Host.h instead.
Instead of getting the endianness from configure,
calculate it directly.

Dan Gohman 7a7742c2fe Allow vector integer constants to be created with 
SelectionDAG::getConstant, in the same way as vector floating-point
constants. This allows the legalize expansion code for @llvm.ctpop and
friends to be usable with vector types.

Anton Korobeynikov 7ab71379b6 Use vector for child storage instead of map. This will also make 
our life during future GraphTraits'ing slightly easier.

Duncan Sands 9ab0943b86 Revert r44626, which turned off the use of readonly 
and readnone for functions with bodies because it
broke llvm-gcc-4.2 bootstrap.  It turns out that,
because of LLVM's array_ref hack, gcc was computing
pure/const attributes wrong (now fixed by turning
off the gcc ipa-pure-const pass).

Wojciech Matyjewicz 309e5a723b 1. "Upgrage" comments. 
2. Using zero-extended value of Scale and unsigned division is safe provided
   that Scale doesn't have the sign bit set.
   Previously these 2 instructions:
        %p = bitcast [100 x {i8,i8,i8}]* %x to i8*
        %q = getelementptr i8* %p, i32 -4
   were combined into:
        %q = getelementptr [100 x { i8, i8, i8 }]* %x, i32 0,
               i32 1431655764, i32 0
   what was incorrect.

Owen Anderson 499e5bffcf Forgot to remove a register from the PHI-union after I'd determined that it 
interfered with other registers.  Seems like that might be a good thing to do. :-)

Bill Wendling 5143d898c8 Checking for "zero operands" during the "CanHoistInst()" method isn't necessary 
because those with side effects will be caught by other checks in here.

Also, simplify the check for a BB in a sub loop.
