cdc4657988 Handle constant addresses more efficiently, folding the low bits into the 
disp field of the load/store if possible.  This compiles
CodeGen/PowerPC/load-constant-addr.ll to:

_test:
        lis r2, 2838
        lfs f1, 26848(r2)
        blr

instead of:

_test:
        lis r2, 2838
        ori r2, r2, 26848
        lfs f1, 0(r2)
        blr

dc3605efdb Add support for generating vspltw, instead of a vperm instruction with a 
constant pool load.  This generates significantly nicer code for splats.

When tblgen gets bugfixed, we can remove the custom selection code.

7955a187b1 - Fixed a bogus if condition. 
- Added more debugging info.
- Allow reuse of IV of negative stride. e.g. -4 stride == 2 * iv of -2 stride.
