[PATCH] D48555: Account for undef values from predecessors in extendSegmentsToUses

[Krzysztof Parzyszek via Phabricator via llvm-commits]

The code itself is of a very reasonable size, I just meant removing the unnecessary fields from the machine function description, i.e. register classes (because they are specified inline), frame info, etc.  Basically anything that is set to its default values.  Testcases can be hard to generate for issues like this, so thank you for making effort to get them.
