Force user provided warning and error messages to only occupy one line.
PR 84195
gcc: * tree.c (escaped_string): New class. Converts an unescaped
string into its escaped equivalent.
(warn_deprecated_use): Use the new class to convert the
deprecation message, if present.
(test_escaped_strings): New self test.
(test_c_tests): Add test_escaped_strings.
* doc/extend.texi (deprecated): Add a note that the
deprecation message is affected by the -fmessage-length
option, and that control characters will be escaped.
(#pragma GCC error): Document this pragma.
(#pragma GCC warning): Likewise.
* doc/invoke.texi (-fmessage-length): Document this option's
effect on the #warning and #error preprocessor directives and
the deprecated attribute.
testsuite;
* gcc.c-torture/compile/pr84195.c: New test.
