The test assumed that `ggatel create` created a device on completion, but that's
incorrect. This squashes the race by waiting for the device to appear, as
`ggatel create` daemonizes before issuing an ioctl to geom_gate(4) if not called

Derived from an implementation by Mark Adler.
The fast loop performs three simultaneous CRCs over subsets of the data
before composing them. This takes advantage of certain properties of
the CRC32 implementation in Intel hardware. (The CRC instruction takes 1
cycle but has 2-3 cycles of latency.)
The CRC32 instruction does not manipulate FPU state.
i386 does not have the crc32q instruction, so avoid it there. Otherwise
the implementation is identical to amd64.
Add basic userland tests to verify correctness on a variety of inputs.

Ideally we'd have a top level hwpmc module with the shared bits, then
cpu specific glue as needed. However, on the MIPS side, there's no
probe code - {mips24k, mips74k, octeon} implement a set of methods
that hwpmc_mips.c expects.
So this populates separate modules with duplicate code.
Ew, but it does work.
This gets me off the hook - these work fine as copied into the relevant
mfsroot for mips24k/mips74k systems.
TODO:
* do it the "right" way in the future. Note that modules/hwpmc/ does
build fine on MIPS, it jusn't DO anything. So it'd be nice to
maybe call that "hwpmc_core" and then "hwpmc" can be the CPU/arch glue.

[SROA] Remove incorrect assertion
Confirmed with aprantl, this assertion is incorrect - code can get
here (for example 80-bit FP types) and if it does it's benign. This
is exposed by a completely unrelated patch of mine, so stop the
compiler falling over.

The checks have quadratic complexity over a number of advisory locks
active for a file and that could be a lot. What's the worse is that the
checks are done while holding ls_lock. That could lead to a long a very
long backlog and performance degradation even if all requested locks are
compatible (e.g. all shared locks).
The checks used to be under INVARIANTS.

Clang complains about the shift of (1 << 7) into a int8_t changing the value:
warning: implicit conversion from 'int' to 'int8_t' (aka 'signed char') changes
value from 128 to -128 [-Wconstant-conversion]
Squash this warning by forcing clang to see it as an unsigned bit.
This seems odd, given that it's still a conversion of 128->-128, but I'm
guessing the explicit unsigned attribute notifies clang that sign really doesn't
matter in this case.

This may lead to legitimate problems with aggressive optimizations, if not now
then in the future. To avoid this, add a new enum, INTR_TRIG_INVALID, set to
-1, and use this new enumeration in these checks.
