[LLVMdev] GetConstantBuildVectorBits, isConstantSplat

[Scott Michel]

Is anyone going to develop acute heartburn if I move these two functions as
TargetLowering methods? It seems that they're used frequently enough across
multiple backends and provide common functionality.

I could be convinced that TargetLowering is the wrong place to put these
functions as methods and that they're better off in a separate BUILD_VECTOR
SDValue class.

Comments?
