[PATCH] D31750: [globalisel] Enable tracing the legalizer with --debug-only=legalize-mir

[Daniel Sanders via Phabricator via llvm-commits]

SmallVector -> number of new instructions emitted.

Also fixed a small issue I missed in the refresh. Now that the debug output
code is split across two files with different DEBUG_ONLY definitions you need
--debug-only=legalize-mir,legalizer to get useful debug output. legalize-mir
isn't a pass and doesn't provide useful debug output without legalizer so I've
made them both enable their debug output when given --debug-only=legalizer.
