* Fixing issue 1898 Preserve sign for number with underflowing exponent (#1900)
Before this commit, simdjson parsed "-1e-999" and "-0e-999" and "-1e-342"
as 0.0.
After this commit, those JSON strings get parsed as -0.0.
(https://en.wikipedia.org/wiki/Signed_zero)
The old behavior was inconsistent with the way simdjson parsed "-0.0" as -0.0.

* 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)
