1e083ec1f6 x86-32 long doubles are 4-byte aligned on the stack 
for parameter passing (only for that, on Darwin).

d76f256282 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.

0075ea1f5f 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.

our life during future GraphTraits'ing slightly easier.

998cd21867 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).

8bb1d9e67c 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.
