evas: Inline part of clip_dirty

clip_dirty is called A LOT. Unfortunately this patch does not
result in very measurable improvements.

**********************
Note about this merge:

After this series of patches, the CPU usage for a certain test
case has significantly gone down:

Based on c0e6a8d698c17fc16f9b67fc9 (upstream before git push):
NS since frame 2 = 28910806786 , 2937 frames = 9843652 / frame

After this patch:
NS since frame 2 = 19218592951 , 2928 frames = 6563727 / frame

1.18:
NS since 2 = 13105584220 , 2961 frames = 4426066 / frame

As we can see, 1.18 remains *much* better than 1.19. I'm still
struggling trying to figure out why (clip_recalc is called more,
but the call tree is hard to decypher).

The test case is:
EINA_FREEQ_BYPASS=1 ELM_TEST_AUTOBOUNCE=100 \
  elementary_test -to "Scroller 2"

EFL was compiled with GCC 6.3.1 with -O3 -g
