Verify occlusion query correctness in a multi-view context
The patch adds tests to verify that an occlusion query correctly tracks
whether any fragments pass the depth test for any of the views as
according to the ANGLE_multiview extension.

Modify attribute divisor for multiview instanced rendering
If the ANGLE_multiview extension is used in a program, the number
of geometry instances is the number of instances passed to
glDraw*Instanced times the number of views in the program. The attribute
divisor has to be multiplied by the number of views so that the correct
attributes are gathered in the input assembly stage.

Handle multiview Draw* calls
Because the ANGLE_multiview extension uses instancing to multiply
geometry for each view, Draw* calls with an active multiview program
have to be handled in the follwing way:
1) Convert non-instanced Draw calls to their instanced versions.
2) Multiply the number of instances in an instanced Draw call by the
number of views.

Disallow timer queries with multi-view draw framebuffers
According to the ANGLE_multiview spec Draw* commands should generate
an INVALID_OPERATION error if there is an active query object for
target TIME_ELAPSED_EXT and the number of views in the active draw
framebuffer is greater than 1.

Disallow active transform feedback with a multi-view draw framebuffer
According to the ANGLE_multiview spec Draw* commands should generate
an INVALID_OPERATION error if there is an active transform feedback
object and the number of views in the active draw framebuffer is greater
than 1. The patch addresses this by extending the base draw call
validation.

Generate error on program-framebuffer num views mismatch
According to the ANGLE_multiview spec Draw* commands should generate
an INVALID_OPERATION error if the program uses the multiview extension
and the number of views in the active draw framebuffer and active
program differs. The patch addresses this by extending the base draw
call validation.
