SVN commit r230979 always associates a loop's back-jump with the start
of the loop body. This caused a regression for gcov with conditional
loops, because then the loop body appears to be covered twice per
iteration.

PR gcov-profile/68603
* cp-gimplify.c (genericize_cp_loop): For the back-jump's location
use the start of the loop body only if the loop is unconditional.

The errors reported by check_attr_value weren't very helpful because
they always used the location of the define(_enum)_attr, even if the
error was in a define_insn. Also, the errors reported by
check_attr_test didn't say which attribute was faulty.
Although not technically a bug fix, it was really useful in writing
the patch for PR68432.
Tested on a variety of targets.
