Platform.h is out of control Part 3: Move all ENABLE_* macros definitions in FeatureDefines.h
​https://bugs.webkit.org/show_bug.cgi?id=206139

Reviewed by Anders Carlsson.

  • Moves all remaining ENABLE_* defines out of Platform.h and into FeatureDefines.h
  • Moves most, USE_UDIS86 and USE_ARM64_DISASSEMBLER are tangled up in the JIT definitions still, HAVE_* and USE_* defines out of FeatureDefines.h and into Platform.h
  • Where straigthforward, convert macro definitions into a canonical 3 line entry of the form:


#if !defined(MACRO_NAME) && (<CONDITIONS HERE>)
#define MACRO_NAME 1
#endif

There is rarely (if ever) a resone to undefine or define one of these platform related
macros to 0 as the usage macros (e.g. HAVE(...), ENABLE(...), etc.) handle undefined as 0.

  • Added a guard so that FeatureDefines.h can't be included directly, and must be included via Platform.h. This is necessary as it depends heavily on macros defined in Platform.h
  • Added numerous FIXMEs detailing follow up cleaning.
