When -fsanitize-address-use-after-scope is used, the instrumentation produces line numbers in stack frame descriptions. This patch make sure the ASan runtime supports this format (ParseFrameDescription needs to be able to parse "varname:line") and prepares lit tests to allow line numbers in ASan report output.
