[LLVMdev] opt and llc use datalayout differently - bug?

Hi JP,

llc completely ignores the target datalayout because it already knows how
the target lays out data.  Target datalayout exists entirely for the
benefit of opt: it allows opt to use target specific information without
having to be linked with the code generators.

Ciao, Duncan.
