Fix crashes due to AMD driver bugs.

programBinariesTest() failure was due to AMD drivers crashing
in clCreateKernelsInProgram() when the program is not built yet,
instead of returning error code CL_INVALID_PROGRAM_EXECUTABLE as they
should.

lowLevelVectorAddTest() failure was apparently due to the AMD drivers
writing past the end of a direct byte buffer in such a way that it made
System.gc() crash when called during teardown (this crash didn't even
dump stack). Making the buffer larger solved the problem.
