[PATCH] D141323: AMDGPU: Use constant and externally_initialized for block handle

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

I posted the g version of this, still needs the undef initializer. available_externally and constant initializer are the useful parts, and can use undef initializer. the zeroinitializer was pointless since it's overwritten
