Hi,
This patch sets the TYPE_ARTIFICIAL flag on internally generated
object.TypeInfo types, preventing them from triggering warnings when
compiling with `-Wpadded'.
Regression tested on x86_64-linux-gnu/-m32/-mx32, committed to mainline,
and backported to the release/gcc-10, gcc-11, and gcc-12 branches.
Regards,
Iain.
