Chris Lattner a2165ed6ee Allow aliasee to be a GEP or bitcast instead of just a bitcast.
The real fix for this whole mess is to require the operand of the
alias to be a *GlobalValue* (not a general constant, including 
constant exprs) but allow the operand and the alias type to be
unrelated.

This fixes PR4066
