[codeview] Don't assert if the array element type is incomplete This can happen when the frontend knows the debug info will be emitted somewhere else. Usually this happens for dynamic classes with out of line constructors or key functions, but it can also happen when modules are enabled. llvm-svn: 281060

Renumber testcase metadata nodes after r290153. This patch renumbers the metadata nodes in debug info testcases after https://reviews.llvm.org/D26769. This is a separate patch because it causes so much churn. This was implemented with a python script that pipes the testcases through llvm-as - | llvm-dis - and then goes through the original and new output side-by side to insert all comments at a close-enough location.
