Anders Carlsson fd88a6160d Rename getBaseClassOffset to getBaseClassOffsetInBits and introduce a getBaseClassOffset which returns the offset in CharUnits. Do the same thing for getVBaseClassOffset.

John McCall c273f24196 Better solution: calculate the visibility of functions and variables 
independently of whether they're definitions, then teach IR generation to
ignore non-explicit visibility when emitting declarations.  Use this to
make sure that RTTI, vtables, and VTTs get the right visibility.

Douglas Gregor ae498b3211 The global variable for the VTT might not have external linkage; allow 
us to find local variables, too. Fixes the last remaining
Boost.Rational failure.
