* 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)
