61c70e98ac remove unions from LLVM IR. They are severely buggy and not
being actively maintained, improved, or extended.

This is in preparation for generalizing its parsing of function-local
values.

4ba9d9b67b fix a crash on invalid metadata, e.g.: call i32 @foo(), XXXX
We would return the error without inserting the new instruction
into the program, so it wouldn't get deallocated, and an abort
would trigger when the module was deleted.

449c3103c5 rewrite handling of forward ref'd instruction metadata
to used deferred resolution instead of creating a temporary
node + rauw.  There is no reason to create the temporary
mdnode, then do rauw, then destroy it.
