expectation is that frequency throttling in these cases is less of a concern for most users.
To be clear, older Intel processors with AVX-512 instructions (such as cascade lake or skylake-x)
will not be able to run AVX-512 instructions.
2. We adopt a much faster bitset decoding technique described in the following blog post:

3. The compress method which is used by _mm512_mask_compressstoreu_epi8 should be a massive performance
gain but also a drastic reduction in code complexity.
4. I try to catch up on crediting valued contributors.
* Change the implementation name from cascadelake to icelake.
* Do VBMI2 check, so as to run AVX512 only on the newer Intel processors.

* Optimized the arm64 implementation of simd8x64::compress
This is ~35% faster on the fast_minify benchmarks on Apple M1
* Return byte-count from simd8x64::compress
This avoids a redundant popcount on ARM, for ~3% faster minify
on Apple M1
* This exposes 'rewind' for object and array instances.
* Putting really_inline back to count_elements()
* Update array.h
* Adding empty array rewind.
* Adds "is_empty" method to arrays.
* More fragmentation.
* Tweaking implementation.
* Fixing issue with get_value() on document instances.
* Changing the name of the new rewind functions to reset.
Including <iostream> has two problems:
* Compile times are worse because of over-inclusion
* Binary sizes are worse when statically linking libstdc++ because
iostreams cannot be dead-code-stripped
simdjson only needs std::ostream. Include the header declaring only what
we need (<ostream>), omitting stuff we don't need (std::cout and its
initialization, for example).
This commit should not change behavior, but it might break users who
assume that including <simdjson/simdjson.h> will make std::cout
available (such as many of simdjson's own files).
* Adding test.
* Verifies and fix issue 1668. This commit updates the previous behavior of the
On Demand stream support by return a value type (document_reference) instead
of a reference to a document. This allows us to bridge with the usually simdjson
error system, with its simdjson_result types.
* Minor reformat.
* Adds a test with initial tests passing.
* Adding an example.
* Update basic.md to document JSON pointer for On Demand.
* Add automatic rewind for at_pointer
* Remove DOM examples in basics.md and update documentation reflecting addition of at_pointer automatic rewinding.
* Review
* Add test
* Naive implementation for doubles in string.
* Add double from string in atom doc.
* Simplification (removed all *_from_string())
* Add int and uint parsing in string.
* Make duplicates instead.
* Make tests exceptionless.
* Add missing declarations.
* Add more tests (errors, JSON pointer).
* Add crypto json tests.
* Update doc.
* Update doc after review.
