Francisco Geiman Thiesen 90e4a66c93 Bringing a bit more use-cases for reflection based serializations (optional). Also adding string-based enum handling as requested on X. (#2395)
* Adding type validation, enhancing optional type support and adding test a few more tests.

* Adding support for string-based enum serlalization and deserialization.

* Removing unintentional endline.

* Removing trailing whitespace.

* Adding simpler api as suggested by moisrex.

* Removing explicit optiona<int> and optional<std::string> references and using concepts instead! Credit goes to Lemire for pointing this out and suggesting a concepts based approach here.

* Removing tests that are not relevant for this branch.

* Removing api related changes. That will be done by moisrex.

* Removing unnecessary new endlines.

* Removing tests related to api changes and cleaning-up irrelevant tests.

* removing broken reference

strager 5510089d45 Improve build times for debug builds (#1859)
* Rename simdjson_really_inline -> simdjson_inline

I want to change the simdjson_really_inline macro to sometimes not force
inlining. After that upcoming change, the name simdjson_really_inline
will no longer makes sense.

Rename simdjson_really_inline to simdjson_inline. This patch should not
change semantics; simdjson_inline still forces inlining as before.

Some functions still need to be really inlined for ABI reasons.
(GCC's -Wpsabi complains otherwise.) Leave those functions marked as
simdjson_really_inline.

* Improve build times for debug builds

simdjson_inline is used for most simdjson functions. It forces inlining.
In unoptimized/debug builds, this can lead to a lot of machine code
being generated (especially with Address Sanitizer), causing slow
compilation.

Change simdjson_inline to force inlining only for optimized builds.

Sometimes, the programmer might want a slightly-optimized build and want
fast compilation (e.g. GCC's -Og mode). Allow simdjson users to define
the simdjson_inline macro themselves (e.g. on the command line:
-Dsimdjson_inline=inline) in cases where the default behavior is
undesired.

This patch reduced build times by over 75% for ondemand_object_tests.cpp
with GCC 9.4.0 and CMAKE_BUILD_TYPE=Debug on my AMD 5950X:

Before: 6.885 6.683 6.971 6.957 6.949 seconds (5 samples)
After:  1.492 1.551 1.494 1.490 1.531 seconds (5 samples)
