Fix thinko in UnwindTable.cpp where it wouldn't provde a 
FuncUnwinders object if the eh_frame section was missing
from an objfile.  Worked fine on x86_64 but on i386 where
eh_frame is unusual, that resulted in the arch default 
UnwindPlan being used all the time instead of picking up
an assembly profile based unwindplan.
