[metal/hlslcc/runtime][OSX] Slightly bigger CPU/GPU frame time on OSX Metal builds

OSX

-

Steps to reproduce:

1. Open attached project
2. Change graphics API to 'Metal' for Mac Standalone
3. Build 'DEMO INFINIGRASS v1.3 UNGROWN-Gradual Growth' scene
4. Attach the built app to Xcode project and observe the CPU/GPU frametime (this can only be done in macOS Sierra update, previous OSX versions don't have this functionality)

Repeat these steps with 5.5.0 (trunk) and metal/hlslcc/runtime branch, notice the big difference in both CPU and GPU frame time.

My results:
trunk:
CPU: 17 - 18ms
GPU: 17 - 19ms
metal/hlslcc/runtime:
CPU: 19 - 20ms
GPU: 19 - 20ms
