Fix the DTrace pid return trap interrupt vector. Previously we were using
31, but that vector is reserved.

Without this fix, running dtrace -p <pid> would either cause the target
process to crash or the kernel to page fault.

Add two DTrace trap type values. Used by fasttrap.

Activate SSE/SIMD. This is the extra context switching support that
we are required to do if we let user processes use the extra 128 bit
registers etc.

This is the base part of the diff I got from:

I have fixed a couple of style(9) deviations. I have some followup
commits to fix a couple of non-style things.

Removed all traces of T_ASTFLT (except for gaps where it was). It became
unused except in dead code when ast() was split off from trap().

Exchange numerical values for FPE_INTDIV and FPE_INTOVF, so that they
are compatible with the older ones implemented in FreeBSD 3.x.

Various formatting fixes on my FPE trapcode commit.

On FPU exceptions, pass a useful error code (one of the FPE_...
macros) to the signal handler, for old-style BSD signal handlers as
the second (int) argument, for SA_SIGINFO signal handlers as
siginfo_t->si_code. This is source-compatible with Solaris, except
that we have no <siginfo.h> (which isn't even mentioned in POSIX
1003.1b).

An rather complete example program is at
http://www3.cons.org/cracauer/freebsd-signal.c
This will be added to the regression tests in src/.

This commit also adds code to disable the (hardware) FPU from
userconfig, so that you can use a software FP emulator on a machine
that has hardware floating point. See LINT.
