Hal Finkel c818be073d [bugpoint] Fix "Alias must point to a definition" problems ... GlobalAliases may reference function definitions, but not function declarations. bugpoint would sometimes create invalid IR by deleting a function's body (thus mutating a function definition into a declaration) without first 'fixing' any GlobalAliases that reference that function definition. This change iteratively prevents that issue. Before deleting a function's body, it scans the module for GlobalAliases which reference that function. When found, it eliminates them using replaceAllUsesWith. Fixes PR20788.
