suppose I have some bitcode that contains target data in it.
If I run "opt -inline" on it, will the target information be
used?  Since the inliner no longer requires target data, maybe
the TargetData pass won't be run at all, causing
   getAnalysisIfAvailable<TargetData>() to return NULL, and
target data not to be used even though present in the bitcode.

Ciao,

Duncan.
