1f0e9e4e11 rand: add enumValueWithIndex 
and reimplement enumValue in terms of it. Same rationale as shuffleWithIndex. Share small piece of code through MinArrayIndex.

8828fe3a7d rand: add shuffleWithIndex 
and reimplement shuffle in terms of it. This allows the caller to specify an index type of a fixed bit width, allowing results to be independent usize.

907f3ef887 crypto.salsa20: make the number of rounds a comptime parameter (#13442) 
...instead of hard-coding it to 20.

- This is consistent with the ChaCha implementation
- NaCl and libsodium, that this API is designed to interop with,
also support 8 and 12 round variants. The 12 round variant, in
particular, provides the same security level as the 20 round variant,
but is obviously faster.
- scrypt currently uses its own non optimized version of Salsa, just
because it use 8 rounds instead of 20. This will help remove code
duplication.

No behavior nor public API changes. The Salsa20 and XSalsa20 still
represent the 20-round variant.

694d8831c3 Revert "x86" CPU model (not arch) back to "i386" 
PR #13101 recently renamed the "i386" architecture to "x86", and it
seems the specific CPU model got swept up in that. "x86" is an umbrella
term that describes a family of CPUs, and the "i386" is the oldest
supported model under that umbrella.

0d192ee9ef std.crypto.onetimeauth.Ghash: make GHASH 2 - 2.5x faster (#13374) 
Rewrite GHASH to use 128-bit multiplication over non-reversed
integers, and up to 8 blocks aggregated reduction.

lib/std/crypto/benchmark.zig results:

Xeon E5:
  Before: 1604 MiB/s
   After: 4005 MiB/s

Apple M1:
  Before: 2769 MiB/s
   After: 6014 MiB/s

This also makes AES-GCM faster by the way.

d02242661e std.heap: make wasm32 PageAllocator handle large allocation 
When a number of bytes to be allocated is so great that alignForward()
is not possible, return `error.OutOfMemory`.

* std.os.uefi: integer backed structs, add tests to catch regressions

device_path_protocol now uses extern structs with align(1) fields because
the transition to integer backed packed struct broke alignment

added comptime asserts that device_path_protocol structs do not violate
alignment and size specifications

348f73502e Make MAX_NAME_BYTES on WASI equivalent to the max of the other platforms 
Make the test use the minimum length and set MAX_NAME_BYTES to the maximum so that:
- the test will work on any host platform
- *and* the MAX_NAME_BYTES will be able to hold the max file name component on any host platform

c5d23161fc Set wasi MAX_NAME_BYTES to minimum of the rest of the supported platforms 
This is a slightly weird situation, because the 'real' value may depend on the host platform that the WASI is being executed on.

c6ff1a7160 Windows: Fix iterator name buffer size not handling all possible file name components
