configure: support sanitizers
It is now possible to run ./configure --with-sanitizer=address
(or any least of valid sanitizers) to build with sanitizers.
When --with-sanitizer is specified, we build with -O1 and
don't omit frame-pointer. We also enable RTTI (which should
be enabled anyway, but just in case).
UBSan (undefined) sanitizer can cause 'typeinfo' errors.
Fixing the source is best, but as a workaround, disabling
vptr sanitizer works. Just pass -fno-sanitize=vptr to CFLAGS
and CXXFLAGS.
