Duncan P. N. Exon Smith 754cf7920b DebugInfo: Add implicit conversion from DISubprogram to DIScope
As a follow-up to r234850, add an implicit conversion from
`DISubprogram` to `DIScope` to support Kaleidoscope Ch. 8.  This also
reverts that band-aid from r234890.

(/me learns *again* to build Kaleidoscope before commit...)
