* Updating main branch for legacy libc++ support
* Adopting
* Removing unnecessary math header.
* Updating the single-header files so we can pass the new tests.
* Portable infinite-value detection is hard.

* Selectively disabling Boost JSON
* More work toward selectively disabling boost json.
- Allow user to specify SIMDJSON_BUILTIN_IMPLEMENTATION
- Make cmake -DSIMDJSON_IMPLEMENTATION=haswell *only* specify haswell
- Move negative implementation selection to
-DSIMDJSON_EXCLUDE_IMPLEMENTATION
- Automatically select SIMDJSON_BUILTIN_IMPLEMENTATION if
SIMDJSON_IMPLEMENTATION is set
- Move implementation enablement mostly to implementation files
- Make implementation enablement and selection simpler and more robust
- Fix bug where programs linked against simdjson were not passed
SIMDJSON_XXX_IMPLEMENTATION or SIMDJSON_EXCEPTIONS
* This would disable bash scripts under FreeBSD.
* Let us also disable GIT.
* Let us try to just disable GIT
* Nope. We must have both bash and git disabled.
C++ 20 adds a new feature called "ranges", which provides components for dealing
with sequences of values: https://en.cppreference.com/w/cpp/ranges.
A range is like a normal object containing `begin` and `end`, except there are
also composable operations like maps, filters, joins, etc.
The iterator objects returned by a range's `begin` and `end` require a more
strict set of operations than is needed for a range-for loop.
This PR adds the extra operations needed to support turning `dom::array` and
`dom::object` into a range.
This PR does not depend on any C++ 20 behavior, the added operators are all
valid C++ 11, and are already part of the LegacyIterator concepts.
This PR adds extra code behind: `#if defined(__cpp_lib_ranges)` guards, which is
the new C++ 20 specified feature test macro for ranges support. When ranges
support is detected, extra compile time checks are added to ensure that
`dom::array` and `dom::object` satisfy the range concept. No runtime tests have
been added yet because these compile time checks should be sufficient.
If desired, the `static_assert` code could be moved out of the actual code
headers and put into a test file.
