What is inconvenient is that sometimes I need to see RTL after each

subpass in question.
I've added dumping of the RTL after each subpass.
So this approach would be useful at least for me in some cases. But I
think it should be not a default approach
I've added an option flra-split-dump, off by default.
The dump files look like:
...
$ ls -1 reduc-1.c.278r.reload*
reduc-1.c.278r.reload
reduc-1.c.278r.reload.001.remove_scratches
reduc-1.c.278r.reload.002.lra_constraints

reduc-1.c.278r.reload.023.lra_constraints
reduc-1.c.278r.reload.024.lra_finishing
...
The main dump file "reduc-1.c.278r.reload" contains all the dumping that
is done by the pass manager, not by the lra pass itself.
Bootstrapped and reg-tested on x86_64.
Any further comments?
The new option needs a help string in the .opt file and documentation in
invoke.texi, no?
