binutils/testsuite: Support stderr options with `run_dump_test'
Add support for the `error', `error_output', `warning' and `warning_output' options for `run_dump_test' input files, based on the version of the procedure in ld/testsuite/lib/ld-lib.exp and providing compatible semantics. These options apply to PROG under test and let test cases specify output expected on stderr as well as express a requirement for PROG to exit unsuccessfully. Messages to match against can be supplied either inline or fetched from a named file. Update procedure description in the introductory comment accordingly. As the exit status from `remote_exec' is regrettably lost in our default implementation of `binutils_run', which is user-overridable, avoid changing this procedure's API and use a global `binutils_run_status' variable to pass the status up to the caller, similarly to how `binutils_run_failed' is handled. Document the new variable in the respective introductory comments. binutils/ * testsuite/config/default.exp (binutils_run): Document `binutils_run_status'. * testsuite/lib/utils-lib.exp (default_binutils_run): Likewise, and set it. (run_dump_test): Add `error', `error_output', `warning' and `warning_output' options. Update documentation accordingly.
