[LLVMdev] Type get size

[Scott Ricketts]

Ah, I needed some target-dependent stuff (TargetData) to make this work.

I used TargetData::getTypeSizeInBits(const Type* Ty). Also, I added:

AU.addRequired<TargetData>();

to getAnalysisUsage(AnalysisUsage &AU) for my pass struct.

There are a few other options for getting type size from TargetData
(e.g. getTypeAllocSize).
