Move FP texture test buffers to heap.
This is a speculative fix for the crashing N5 bots. It looks like the bots are
always failing in or around FloatingPointTextureTest.
It looks like sometimes they're hitting a SIGBUS, which I suspect is stack
overflow. FloatingPointTextureTest allocates ~320K on the stack, which may
be too much. This CL moves those buffers to the heap. For consistency I did
the same with the half-float tests, though they're only using ~1/8th the stack.
It looks like sometimes the bots are failing to malloc. I don't understand that,
and this CL doesn't address that directly. But it's possible this is still a stack
overflow, just trashing RAM and causing arbitrary mayhem instead of a SIGBUS.
I have no idea why this is a problem only on the N5. I have been unable to
reproduce this locally, neither with a K N5 nor an L N5, but the bots are pretty
reliable.
