D63932 added a module flag to indicate that we are executing the regular LTO post merge pipeline, so that GlobalDCE could perform more aggressive optimization for Dead Virtual Function Elimination. This caused issues trying to reuse bitcode that had already been through the LTO pipeline (see context in D139816). Instead support this by passing down a parameter flag to the GlobalDCEPass constructor, which is the more usual way for indicating this information. Most test changes are to remove incidental uses of this flag. Of the 2 real uses, llvm/test/LTO/ARM/lto-linking-metadata.ll is now obsolete and removed in this patch, and the virtual-functions-visibility-post-lto.ll test is updated to use the regular LTO default pipeline where this parameter is set to true.
