add a fastpath to ConstantExpr::getBitCast to handle the case when an obviously unneeded bitcast is requested. This is common for frontends who just unconditionally cast even if the target is often the right type already. THis prevents going into getFoldedCast which switches on the opcode and does a bunch of other stuff before doing the same opzn. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@67435 91177308-0d34-0410-b5e6-96231b3b80d8
