Duncan P. N. Exon Smith d397a52305 DebugInfo: Fix testcases with invalid MDSubprogram nodes
Fix testcases that don't pass the verifier after a WIP patch to check
`MDSubprogram` operands more effectively.  I found the following issues:

  - When `isDefinition: false`, the `variables:` field might point at
    `!{i32 786468}`, or at a tuple that pointed at an empty tuple with
    the comment "previously: invalid DW_TAG_base_type" (I vaguely recall
    adding those comments during an upgrade script).  In these cases, I
    just dropped the array.
  - The `variables:` field might point at something like `!{!{!8}}`,
    where `!8` was an `MDLocation`.  I removed the extra layer of
    indirection.
  - Invalid `type:` (not an `MDSubroutineType`).
