(Opening this as a draft PR because it's dependent on new Builtins work that was just merged to main)

Implements a more efficient concrete algorithm for generating random SIMDMask objects. Because each lane of a SIMDMask only needs a single bit of randomness, we can get all the randomness we need from a single call to rng.next(), instead of using a call per lane as happens when we go through Bool.random() in the generic implementation. (We can also improve the generic implementation, which I'll look at next).

SIMDMask.random() is not too heavily used, so we won't see any big wins from this anywhere, but it's a mostly trivial change with some nice speedups.

How to read the data The tables contain differences in performance which are larger than 8% and differences in code size which are larger than 1%.

If you see any unexpected regressions, you should consider fixing the
regressions before you merge the PR.

Noise: Sometimes the performance results (not code size!) contain false
alarms. Unexpected regressions which are marked with '(?)' are probably noise.
If you see regressions which you cannot explain you can try to run the
benchmarks again. If regressions still show up, please consult with the
performance team (@eeckstein).

✅ Benchmark Check Report
⚠️⏱ SIMDRandomMask.Int64x64.Generic execution took at least 1340 μs.
Decrease the workload of SIMDRandomMask.Int64x64.Generic by a factor of 2 (10), to be less than 1000 μs.
How to read the data The tables contain differences in performance which are larger than 8% and differences in code size which are larger than 1%.

If you see any unexpected regressions, you should consider fixing the
regressions before you merge the PR.

Noise: Sometimes the performance results (not code size!) contain false
alarms. Unexpected regressions which are marked with '(?)' are probably noise.
If you see regressions which you cannot explain you can try to run the
benchmarks again. If regressions still show up, please consult with the
performance team (@eeckstein).

@stephentyrone
Add more efficient SIMDMask.random.
48eb7f4
@stephentyrone
Update concrete SIMDMask.random to account for removing VecNxInt1 init.
8164cca
@stephentyrone
Improvements for generic SIMDMask.random, too.
98042fe
@stephentyrone
Introduce concrete implementations of the following SIMD operations:
dffa18c 
- any(_:SIMDMask), all(_:SIMDMask)
- .min(), .max(), .wrappingSum()

Also adds test coverage to make sure we match the existing generic implementations and an internal binding for the x86 MOVMSK instructions.
