Correct the array index for TEXTURE_*1D_ARRAY, and TEXTURE_*2D_ARRAY
The standard says the array index is evaluated according to
floor(z + 0.5)
but RNDNE is sufficient also for the test cases were z is close to 1.5
and it is likely to hit 1.5, the corner case were RNDNE gives a result
different from above formula.
v5: - Use RNDNE instead of ADD 0.5 and FLOOR (Ilia Mirkin)
- update commit message
Fixes 325 tests from android/cts/master/gles3-master.txt:

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
