Update IDTVEC, KIDTVEC, and KUENTRY to align with _ALIGN_TRAPS instead of
ALIGN_TEXT. For the places where IDTVEC and KIDTVEC are used in ways that
would fail if a trap was inserted, provide IDTVEC_NOALIGN for use directly
after other IDTVEC uses, and KIDTVEC_FALLTHROUGH for places where the code
intentionally falls through to a KIDTVEC. "objdump -d" shows that this
just converts nop-sleds to trap-sleds immediately after an unconditional
jmp, or a retq, iretq, or sysretq.
