Duncan P. N. Exon Smith 85cbe57fc5 IR: Don't track nullptr on metadata RAUW ... The RAUW support in `Metadata` supports going to `nullptr` specifically to handle values being deleted, causing `ValueAsMetadata` to be deleted. Fix the case where the reference is from a `TrackingMDRef` (as opposed to an `MDOperand` or a `MetadataAsValue`). This is surprisingly rare -- metadata tracked by `TrackingMDRef` going to null -- but it came up in an openSUSE bootstrap during inlining. The tracking ref was held by the `ValueMap` because it was referencing a local, the basic block containing the local became dead after it had been merged in, and when the local was deleted, the tracking ref asserted in an `isa`. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@224146 91177308-0d34-0410-b5e6-96231b3b80d8		2014-12-12 19:24:33 +00:00
