ecf276b787 remove unions from LLVM IR. They are severely buggy and not 
being actively maintained, improved, or extended.

c68320f6ad Give ParseInstructionMetadata access to the PerFunctionState object.

0f513e1c22 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.

b0cddaebe0 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.

implement support for it) that the stack should be forcibly realigned in the
prologue (and the process reversed in the epilogue).

c3422a8190 now that instruction metadata is only parsed in one place, eliminate the 
parser-global MDsOnInst vector and make ParseInstructionMetadata return

bfd6a6f096 switch to TrackingVH instead of WeakVH, since these can never 
be RAUW'd and go to null.  This also gets us some sorely lacking
type safety.

e897be280c full asmparser support for blockaddress. We can now do: 
$ llvm-as foo.ll -d -disable-output

next project.  Testcase will go in once that works.
