170e618ef5 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.

ae6cf62861 Cygwin/MinGW: Do not version lto plugins
GCC on Linux already uses liblto_plugin.so directly without
the libtool version suffix, adjust windows GCC to do the same.

gcc/ChangeLog:

	* config.host: Adjust plugin name for Windows.

lto-plugin/ChangeLog:

	* Makefile.am: drop versioning from libtool completely.
	* Makefile.in: regenerate.

8fc8bf801e Enable Intel CET in liblto_plugin.so on Intel CET enabled host
Since ld is Intel CET enabled on Intel CET enabled host, dlopen fails on
liblto_plugin.so if it isn't Intel CET enabled.  Add GCC_CET_HOST_FLAGS
to cet.m4, use it in libiberty and lto-plugin to always enable Intel
CET in liblto_plugin.so on Intel CET enabled host.

On Linux/x86 host, enable Intel CET by default if assembler and compiler
support Intel CET so that the generated liblto_plugin.so can be used on
both CET and non-CET machines.  It is an error to disable Intel CET in
liblto_plugin.so on Intel CET enabled host.
