Bug detailed description:
-----------------------------
It fails on SNB/IVB/HSW/BYT/BDW platforms with mesa master branch, and works
well on 10.1 branch.
Bisect shows:d1b6f6711095cd94e80372e7488aa0189e328d88 is the first bad commit.

meta: Clip src/dest rects in BlitFramebuffer, using the scissor
Fixes piglit's fbo-blit-stretch test on drivers which use the meta path.
(i965: should fix Broadwell, but also fixes Sandybridge/Ivybridge/Haswell
since this test falls off the blorp path now due to format conversion)
V2: Use scissor instead of just mangling the rects, to avoid texcoord
rounding problems. (Thanks Marek)
V3: Rebase on Eric's CTSI meta changes; re-add _mesa_update_state in the
CTSI path so that _mesa_clip_blit sees the correct bounds.
