gcc/ChangeLog:
	* opt-suggestions.c (option_proposer::build_option_suggestions):
	Release "option_values".

From-SVN: r264698

As noted at Cauldron, dumpfile.c currently emits "note: " for all kinds
of dump message, so that (after filtering) there's no distinction between
MSG_OPTIMIZED_LOCATIONS vs MSG_NOTE vs MSG_MISSED_OPTIMIZATION in the
textual output.

This patch changes dumpfile.c so that the "note: " varies to show
which MSG_* was used, with the string prefix matching that used for
filtering in -fopt-info, hence e.g.
  directive_unroll_3.f90:24:0: optimized: loop unrolled 7 times
and:
  pr19210-1.c:24:3: missed: missed loop optimization: niters analysis ends up with assumptions.

The patch adds "dg-optimized" and "dg-missed" directives for use
in the testsuite for matching these (with -fopt-info on stderr; they
don't help for dumpfile output).

The patch also converts the various problem-reporting dump messages
in coverage.c:get_coverage_counts to use MSG_MISSED_OPTIMIZATION
rather than MSG_OPTIMIZED_LOCATIONS, as the docs call out "optimized"
as
  "information when an optimization is successfully applied",
whereas "missed" is for
  "information about missed optimizations",
and problems with profile data seem to me to fall much more into the
latter category than the former.  Doing so requires converting a few
tests from using "-fopt-info" (which is implicitly
"-fopt-info-optimized-optall") to getting the "missed" optimizations.
Changing them to "-fopt-info-missed" added lots of noise from the
vectorizer, so I changed these tests to use "-fopt-info-missed-ipa".

gcc/ChangeLog:
	* coverage.c (get_coverage_counts): Convert problem-reporting dump
	messages from MSG_OPTIMIZED_LOCATIONS to MSG_MISSED_OPTIMIZATION.
	* dumpfile.c (kind_as_string): New function.
	(dump_loc): Rather than a hardcoded prefix of "note: ", use
	kind_as_string to vary the prefix based on dump_kind.
	(selftest::test_capture_of_dump_calls): Update for above.

As reported in
<https://gcc.gnu.org/ml/gcc-patches/2018-09/msg01684.html>, some
fp-int-convert tests fail after my fix for PR c/87390, in Arm /
AArch64 configurations where _Float16 uses excess precision by
default.  The issue is comparisons of the results of a conversion by
assignment (compile-time or run-time) from integer to floating-point
with the original integer value; previously this would compare against
an implicit compile-time conversion to the target type, but now, for
C11 and later, it compares against an implicit compile-time conversion
to a possibly wider evaluation format.  This is fixed by adding casts
to the test so that the comparison is with a value converted
explicitly to the target type at compile time, without any use of a
wider evaluation format.

	PR c/87390

    Fix a bug in the parser code that decides whether a given name should
    be considered exported or not. The function Lex::is_exported_name
    (which assumes that its input is a mangled name) was being called on
    non-mangled (raw utf-8) names in various places. For the bug in
    question this caused an imported package to be registered under the
    wrong name. To fix the issue, rename 'Lex::is_exported_name' to
    'Lex::is_exported_mangled_name', and add a new 'Lex::is_exported_name'
    that works on utf-8 strings.
