Declare aio requests on files from local filesystems safe.
- I allow AIO on reclaimed vnodes, since it is deterministically terminated
- devfs mounts are marked as MNT_LOCAL, but device vnodes have type
VCHR, so the slow device io is not allowed.

libmd: strip local absolute symbols (to link with lld)
Old versions of gas produce an invalid section index. That is ignored by
old versions of ld, but prevents a link with lld.

libcxxrt: add padding in __cxa_allocate_* to fix alignment
The addition of the referenceCount to __cxa_allocate_exception put the
unwindHeader at offset 0x58 in __cxa_exception, but it requires 16-byte
alignment. In order to avoid changing the current __cxa_exception ABI
(and thus breaking its consumers), add explicit padding in the
allocation routines (and account for it when freeing).
This is intended as a lower-risk change for FreeBSD 11. A "more correct"
fix should be prepared for upstream and -CURRENT.
