[llvm-reduce] Try harder to not create invalid aliases This was done by adding --abort-on-invalid-reduction to remove-function-bodies-used-in-globals.ll and fixing the fallout. Aliases must have a GlobalValue or ConstantExpr aliasee and the aliasee must be a definition if it's a GlobalValue. Don't RAUW functions with null if there's an alias pointing to it, and similarly don't delete the body of a function. Don't delete the entire body of a function when reducing blocks, preserve at least one block. Also make debugging these sorts of things easier by dumping the module when --abort-on-invalid-reduction triggers.

[llvm-reduce] Allow writing temporary files as bitcode. Textual LLVM IR files are much bigger and take longer to write to disk. To avoid the extra cost incurred by serializing to text, this patch adds an option to save temporary files as bitcode instead.
