[iOS] Significant GPU frametime increase when drawing primitives (cubes/planes/spheres) in 5.5 on A7 devices

iOS

-

Steps to reproduce:

1. Open attached project
2. Build 'cubes' scene for iOS
3. Go to 'Product/Scheme/Edit Scheme', change GPU frame capture to 'Metal' and disable Metal API validation
4. Build the project to A7 device (tested iPad Air and iPad Mini 2)
5. Go to 'Debug Navigator' in Xcode and select 'FPS' tab
6. Notice that GPU frame time is very big (in my tests, around 77ms)

Reproduces on Metal, GLES3 and GLES2, very similar results on all three.

On 5.4.0f3 GPU frame time is ~15ms on same devices.
