Teach GlobalOpt to delete aliases with internal linkage (after forwarding any uses). GlobalDCE can also do this, but is only run at -O3. llvm-svn: 90850 2009-12-08 11:10:20 +01:00			`; RUN: opt < %s -globalopt -S \| FileCheck %s`
If the target of an alias has internal linkage, then the alias can be morphed into the target. Implement this transform, and fix a crash in the existing transform at the same time. llvm-svn: 64583 2009-02-15 10:56:08 +01:00

Update Transforms tests to use CHECK-LABEL for easier debugging. No functionality change.
