[PATCH] D64176: [Bugpoint redesign] Added Pass to Remove Global Variables

[Diego Treviño via Phabricator via llvm-commits]

Herald added subscribers: llvm-commits, mgorny.
Herald added a project: LLVM.

This pass tries to remove Global Variables, as well as their derived uses. For example if a variable `@x` is used by `%call1` and `%call2`, both these uses and the definition of `@x` are deleted. Moreover if `%call1` or `%call2` are used elsewhere those uses are also deleted, and so on recursively.

I'm still uncertain if this pass should remove derived uses, I'm open to suggestions.
