[PATCH] D98888: [AMDGPU] SIOptimizeExecMaskingPreRA should check constant bus constraint when folds EXEC copy

[Alexander via Phabricator via llvm-commits]

alex-t added a comment.

With the change test checks for the COPY but w/o change, it reports "Bad machine code" error because of the "-verify-machineinstrs".
It may be changed just to report "expected string not found..." by removing "-verify-machineinstrs".
