[PATCH] D112852: [GlobalISel] Allow DBG_VALUE to use invalid vregs throughout pipeline

[Matthias Braun via Phabricator via llvm-commits]

MatzeB added a comment.

Before we weaken the verifier, do we have an idea how much benefit we get from allowing these half-initialize vregs? Is searching for these `DBG_VALUE` at the end of GlobalISel and remove them there an option?
