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.
getpagesize() to size_t. For some reason getpagesize() is defined to
return int, and several of the page counts we get come back from the
kernel as int32_t; in LP64 without the cast the byte count will be
computed in a 32-bit value and for large processes will overflow and
become negative... and then remain negative when divided by 1024 to
convert to kilobytes.
Fixes a problem I hit the other day where I saw negative RSS, which
turns out also to be PR 40642.
Note: other logic in here will break down when we first get >2TB
processes... and int32 page counts will break on >8TB processes. But
hopefully we won't see any of that for a few years yet.

fixes rump on sparc, at least somewhat.
tested that normal kernels runs fine this with this change, too.
__*_chk functions included by -D_FORTIFY_SOURCE=2, and if the compiler
provides additional protection, it can mask broken functions..
(none of the _chk functions will return or process any data if
the length given is known to be larger than the buffer)
Move all-zero variables from .data to .bss
Use .lcomm for local variables.
Cleanup a bit of assembly.
Clear PSL_IP in the saved ofmsr (was previously done in ofwoea_machdep.c)
