exploits the sparsity of allocated blocks in a range, without
issuing an "are you there?" query for every block in the range.
swap_pager_copy() is not so smart.  Modify the implementation
of swap_pager_meta_free() slightly so that swap_pager_copy()
can use that smarter implementation too.

to the PCB hash.  The function doesn't modify the hash. It always
asserted write lock historically, but with epoch conversion this
fails in some special cases.

When reporting a process' stats, we can't just provide the tty as an
unsigned long, as if we have no controlling tty, the tty would be NODEV, or
-1. Instaed, just special-case NODEV.

Don't depend on CPUTYPE to define powerpcspe CFLAGS, they should be set
unconditionally.  This reduces duplication.  Also, set some CFLAGS as
gcc-only, because clang's SPE support always uses the SPE ABI, it's not an
optional feature.

-mspe=yes/no was deprecated even before GCC 4.2.1 in favor of
-mspe/-mno-spe.  Clang only supports -mspe/-mno-spe.
