.github: update to Go 1.18.1

Also regenerate all of the stubs, we don't need "+build" anymore
because both Go 1.17 and 1.18 use "go:build" for build tags.

qsort: add benchmarks from the standard library

These will let us be more confident that a custom sort algorithm makes
sense to use, especially when e.g. the Go standard library introduces
a new sorting algorithm, we can compare the two.

On my Mac, using the pdqsort from Go 1.19, the relevant timings are:

    Sort8/100000-10 4.91ms ± 0%
    Sort8/1000000-10 60.1ms ± 0%
    StdlibSort8/100000-10 8.16ms ± 0%
    StdlibSort8/1000000-10 103ms ± 0%

    Sort8/100000-10 163MB/s ± 0%
    Sort8/1000000-10 133MB/s ± 0%
    StdlibSort8/100000-10 98.0MB/s ± 0%
    StdlibSort8/1000000-10 77.5MB/s ± 0%

Compared to the Go 1.18 sort algorithm:

    Sort8/100000-10 4.90ms ± 0%
    Sort8/1000000-10 59.0ms ± 0%
    StdlibSort8/100000-10 8.53ms ± 0%
    StdlibSort8/1000000-10 105ms ± 0%

    Sort8/100000-10 163MB/s ± 0%
    Sort8/1000000-10 136MB/s ± 0%
    StdlibSort8/100000-10 93.8MB/s ± 0%
    StdlibSort8/1000000-10 76.0MB/s ± 0%

So the Go standard library sort performance is improving but we are
still about 40% faster than the benchmark.

go.mod: update /x/sys to latest version

It has some new bug fixes we can use.

Also replace a use of the "syscall" package with the x/sys/unix
package, which has a compatible API.
