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.
