sna/gen5: Flush the render cache between operations
When we change the blend mode between operations, it appears that we
must flush the render cache or else we risk render corruption. This is
usually noticeable in rendering of single glyphs.
This was originally fixed for bug 51422, but was reintroduced by
commit 37eb7343be1aeeb90a860096756603a577df1a77

sna/gen5: Inspired by gen4, reorder the flushing
and the desire to reduce the impact of this w/a.

Title:
Random characters in screen text suddenly disappear
Status in “xserver-xorg-video-intel” package in Ubuntu:
Fix Committed
Bug description:
While using my machine, characters suddenly disappear. No character in
particular, not in any single application in particular, and copying
and pasting the text preserves the characters.
Scrolling the text out of view and back into view doesn't affect the
missing characters. Switching between applications may change the
affected characters (possibly due to a redraw operation?)
Restarting often solves the problem, but it comes back after a couple
of hours working. I've attached a screenshot to show you the problem.
I do believe this is different than the bug relating to garbled characters in
a number of ways
1. I don't ever get garbled characters
2. Scrolling out/in of the affected text doesn't re-show the missing
characters, even navigating inside the application has no effect. 3. It's
global, I can even see it on Desktop icon names
