tests/sys/kern/crc32: Check for SSE4.2 before using it
This avoids a SIGILL when running these tests on QEMU (which
defaults to a basic amd64 CPU without SSE4.2).
This commit also tests the table-based implementations in addition to
testing the hw-accelerated crc32 versions.

Separate kernel crc32() implementation to its own header (gsb_crc32.h) and
rename the source to gsb_crc32.c.
This is a prerequisite of unifying kernel zlib instances.

calculate_crc32c: Add SSE4.2 implementation on x86
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.
