  timespec-add,timespec-sub: tune
  
  * lib/timespec-add.c (timespec_add):
  * lib/timespec-sub.c (timespec_sub):
  Simplify by detecting overflow when the two overflow bits of the
  underlying operation differ.  This avoids some gotos and labels
  and conditional branches; GCC 14 x86-64 now generates just one
  conditional branch for the resulting code.  Idea stolen from
  my recent changes to the glibc manual’s time chapter.
  * modules/timespec-add (Depends-on):
  * modules/timespec-sub (Depends-on): Add stdbool.
