There's a problem here... rebaseline.py didn't actually have to modify the
allowed-digests for this test, because it was already passing.

(see this line in
tools/tests/rebaseline/input/json1/Test-Android-GalaxyNexus-SGX540-Arm7-Debug/actual-results.json)
: 
"aaclip_gpu.png" : [ "bitmap-64bitMD5", 11899819492385205974 ],

I need to adjust rebaseline.py such that we only add the "bugs" and
"reviewed-by-human" fields to records that are actually updated.
