Wrong x86 assembler in the kernel 

It seems that even ChatGPT produces better code than one in PARI :―(

According to
   https://www.felixcloutier.com/x86/bsr#flags-affected
the code for bfffo() needs a trailing
  : "cc"

Hope this helps,
Ilya

  P.S.  I did not check clobber-flags descriptors on other embedded assembler…
