The following patch fixes useless asserts in my latest patch

Hi Vladimir,
It seems that this patch caused the following ICE on aarch64-linux-gnu
while building cp-demangle.c:

Sorry, I should have bootstrapped my patch on aarch64.
The asserts actually seems very useful as I found they caught a bug in
my previous patch.
I'll push a patch fixing the problems after finishing bootstraps,
probably in couple hours.
Thank you
