Shokunin 673e75ec86 Render passes: reuse the VRAM backup for later passes of a frame ...

Every pass backed up the display rect (hr colour + stencil and raw mirror
blits, CPU rows) although the previous pass of the same frame had just
restored exactly that backup. On Apple's OpenGL each blit ends the render
pass and submits a command buffer, which was about half of a pass's begin
time. A pass now reuses the previous pass's backup when render_pass.c
vouches that no guest code ran since its restore (same plan, guest clock and
store count unchanged) and the rect, scale and native-wide source match; the
first pass of every frame still takes a fresh backup.

R4 Grand Prix race, 240 Hz interpolated: average pass begin 0.28 -> 0.16 ms.
render_pass_stats reports backups_reused.
