LGTM. Doing the inner computation while observing visibility seems like the 
right thing to do in this case.

+        mayBeVisible
----------------
Just adding my own note  of explanation, since this stuff can be a little hard 
to follow.

This inner linkage query needs to observe visibility in order to get a 
consistent result, even if the calling query (i.e. `getLinkageInternal` in this 
case) has passed in a LVComputationKind indicating we don't need to for the 
LocalDecl. If we don't, we may get results inconsistent with the cached value 
for the enclosing FunctionDecl, hence the assert.
