libsanitizer: Add option to bootstrap using HWASAN This is an analogous option to --bootstrap-asan to configure. It allows bootstrapping GCC using HWASAN. For the same reasons as for ASAN we have to avoid using the HWASAN sanitizer when compiling libiberty and the lto-plugin. Also add a function to query whether -fsanitize=hwaddress has been passed. ChangeLog: * configure: Regenerate. * configure.ac: Add --bootstrap-hwasan option. config/ChangeLog: * bootstrap-hwasan.mk: New file. gcc/ChangeLog: * doc/install.texi: Document new option. libiberty/ChangeLog: * configure: Regenerate. * configure.ac: Avoid using sanitizer. lto-plugin/ChangeLog: * Makefile.am: Avoid using sanitizer. * Makefile.in: Regenerate.
