  -----------
  [JSC] Upstream partial ARMv7 port of InPlaceInterpreter 1/?
https://bugs.webkit.org/show_bug.cgi?id=278921

Reviewed by Keith Miller and Justin Michaud.

This adds current porting efforts of the InPlaceInterpreter to ARMv7.

Changes affecting 64 bit:

 - change Const64Metadata and Const128Metadata field order
   to avoid unaligned loads

 - explicitly define firstStackArgumentSPOffset in CallReturnMetadata
   (improve readability)

 - update an outdated comment

 - remove some macros for pushing/popping floats (no longer used by 64 bit!)
