Do we also need to adjust TSAN? There is a bugreport that KCSAN does work
correctly with the named address spaces.(In reply to Jakub Jelinek from comment

I think it should.
E.g. for
int __seg_fs a;
void
foo (int __seg_fs *p)
{
a = *p;
}
the instrumentation is
_5 = __builtin_return_address (0);
__builtin___tsan_func_entry (_5);

Sorry, the second half of my comment is confusing. To clarify, ASan works fine
for TLS data (the compiler knows that TLS base is at fs:0; libsanitizer uses
some hacks to initialize shadow for TLS
