This change adds support for function linkage and visibility and related attributes. Most of the test changes are generalizations to allow 'dso_local' to be accepted where we aren't specifically testing for it. Some tests based on CIR inputs have been updated to add 'private' to function declarations where required by newly supported interfaces. The dso-local.c test has been updated to add specific tests for dso_local being set correctly, and a new test, func-linkage.cpp tests other linkage settings. This change sets `comdat` correctly in CIR, but it is not yet applied to functions when lowering to LLVM IR. That will be handled in a later change.
