gh18515: extend dumping of PM objects
Include RXf_ flags START_ONLY, WHITE and NULL along with the essentially
similar SKIPWHITE; dump the flags whenever GETRE(pm) succeeds, not only
if there is a check substring.
This allows eg `perl -Dx -e 'split /\s+/'` to show whether the intended
flags have been set.

gh18515: fix special handling of specific split() patterns
Commit 122af31004 acted on the wrong assumption that NEXTOPER() and
regnext() were equivalent, and in fixing a valgrind complaint tried
to simplify code for detecting specific patterns for split() that
merited special-case handling by making them all use regnext().
As a result, the special case /\s+/ was no longer correctly detected,
resulting in a degree of pessimisation.
This commit fixes that, and avoids reading via the calculated 'next'
pointer except for the ops we need (in which cases we know it'll point
to another regop) - for the EXACT case (which we don't need), valgrind
was correctly pointing out that it points to potentially uninitialized
data.
