65b89f598c Add poly1305 and x25519 crypto primitives
These are translated from [monocypher](https://monocypher.org/) which
has fairly competitive performance while remaining quite simple.

Initial performance comparision:

Zig:
 Poly1305: 1423 MiB/s
 X25519:   8671 exchanges per second

Monocypher:
 Poly1305: 1567 MiB/s
 X25519:   10539 exchanges per second

There is room for improvement and no real effort has been made at all in
optimization beyond a direct translation.

87eb95f816 speed up chacha20
The main changes are:

    Unrolling the inner rounds of salsa20_wordtobyte which doubles the speed.
    Passing the slice explicitly instead of returning the array saves a copy (can optimize out in future with copy elision) and gives ~10% improvement.
    Inlining the outer loop gives ~15-20% improvement but it costs an extra 4Kb of code space. I think the tradeoff is worthwhile here.
    The other inline loops are small and can be done by the compiler if it is worthwhile.
    The rotate function replacement doesn't alter the performance from the former.

The modified throughput test I've used to benchmark is as follows. Interestingly we need to allocate memory instead of using a fixed buffer else Zig optimizes the whole thing out.

ecc5464024 Handle unions differently in std.fmt (#1432)
* Handle unions differently in std.fmt

Print the active tag's value in tagged unions. Untagged unions considered unsafe to print and treated like a pointer or an array.

Fixed compile error when passing enum to fmt
Caused by struct printing behavior. Enums are different enough from structs and unions that the field iteration behavior doesn't do what we want even if @memberName didn't error on enums.

5c1ec20c9a MacOS stack traces use the already mmapped executable
...rather than trying to find the executable on the file system.

Also use a more robust PIE offset calculation based on the
available metadata.

And for the last function, use the data that tells the end
rather than assuming 4K.

Also they print in a consistent way with Linux stack traces.
