As the kernel moves each LWP into LSSUSPENDED state, have that LWP save its PCU state for the coredump and release its PCU status since its probably going to be exiting very soon. Make pcu_save_all tolerate for being called for non-curlwp if that lwp belongs to the same process, has a state of LSSUSPENDED, and no PCUs are in use. Make the MD coredump code use pcu_save_all(l) since it'll need to save all the PCU state anyways and can take advantage of the above tests.
