RFR: Fix x86_64 non-PCH build

[Aleksey Shipilev]

Current non-PCH build fails with:

/pool/buildbot/slaves/sobornost/shenandoah-jdkX/build/src/hotspot/share/runtime/javaFrameAnchor.hpp:43:14:
note: forward declaration of ‘class StubAssembler’
 friend class StubAssembler;
              ^~~~~~~~~~~~~
/pool/buildbot/slaves/sobornost/shenandoah-jdkX/build/src/hotspot/cpu/x86/gc/shenandoah/shenandoahBarrierSetAssembler_x86.cpp:773:16:
error: invalid use of incomplete type ‘class StubAssembler’
 #define __ sasm->

/pool/buildbot/slaves/sobornost/shenandoah-jdkX/build/src/hotspot/cpu/x86/gc/shenandoah/shenandoahBarrierSetAssembler_x86.cpp:828:3:

   __ epilogue();
   ^~

Fix:
