Description JF Bastien 2016-09-01 18:23:46 PDT 
The following patch moved things around: https://bugs.webkit.org/show_bug.cgi?id=161499

It seems to upset the cmake build with:

Undefined symbols for architecture x86_64:
  "JSC::JSObject::getPropertySlot(JSC::ExecState*, unsigned int, JSC::PropertySlot&)", referenced from:
      JSC::JSObject::get(JSC::ExecState*, JSC::PropertyName) const in IntlDateTimeFormat.cpp.o
      JSC::JSObject::get(JSC::ExecState*, JSC::PropertyName) const in IntlNumberFormat.cpp.o
  "JSC::JSObject::getNonIndexPropertySlot(JSC::ExecState*, JSC::PropertyName, JSC::PropertySlot&)", referenced from:
      JSC::JSObject::get(JSC::ExecState*, JSC::PropertyName) const in IntlDateTimeFormat.cpp.o
      JSC::JSObject::get(JSC::ExecState*, JSC::PropertyName) const in IntlNumberFormat.cpp.o
ld: symbol(s) not found for architecture x86_64

Sure enough, I nm through all the .o files and all references to getPropertySlot are U.

The non-template functions are huge anyways, it seems optimistic to me that they would *ever* be inlined.

But these are marked ALWAYS_INLINE.  I believe that there are a few places where we actually rely on them being inlined.

You should carefully test performance with such a change.  I'm happy to r+ if you've run JetStream, Speedometer, and PLT3.

Fixed by including JSCInlines.h instead of moving things to .cpp file (Fil and others pointed out that this would have perf implications, etc).

This also fixes the cmake build.
