When transforming a call to a bitcast function into a direct call with cast parameters and cast return value (if any), instcombine was prepared to cast any non-void return value into any other, whether castable or not. Add a new predicate for testing whether casting is valid, and check it both for the return value and (as a cleanup) for the parameters. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45657 91177308-0d34-0410-b5e6-96231b3b80d8 2008-01-06 10:12:28 +00:00			`; RUN: llvm-as < %s \| opt -instcombine -disable-output`
