Module rustc_mir_transform::cleanup_post_borrowck

This module provides a pass to replacing the following statements with Nops

• AscribeUserType
• FakeRead
• Assign statements with a Shallow borrow

The CleanFakeReadsAndBorrows “pass” is actually implemented as two traversals (aka visits) of the input MIR. The first traversal, DeleteAndRecordFakeReads, deletes the fake reads and finds the temporaries read by ForMatchGuard reads, and DeleteFakeBorrows deletes the initialization of those temporaries.
