The diagnostics produced by 'dg-optimized', 'dg-missed' aren't error
diagnostics (fatal, meaning: causes compilation to fail) but rather warning
diagnostics (non-fatal, doesn't cause compilation to fail). Thus, same as
'dg-message', these should use 'saved-dg-warning' instead of 'saved-dg-error',
which then prints: "(test for *warnings*, line [...]) instead of currently:
"(test for *errors*, line [...])".
This is a small bug-fix for commit ed2d9d3720adef3a260b8a55e17e744352a901fc
"dumpfile.c: use prefixes other than 'note: ' for
MSG_{OPTIMIZED_LOCATIONS|MISSED_OPTIMIZATION}", which added 'dg-optimized',
'dg-missed'.

* lib/gcc-dg.exp (dg-optimized, dg-missed): Use 'saved-dg-warning'
instead of 'saved-dg-error'.
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
