Log:
[NFC] [GPUJIT] Print line number & size information on allocateMemoryForDeviceCuda failure

- It's useful to know the amount of memory asked for since, for example,
  asking for `0` bytes of memory is illegal.

- Line number is helpful since we print the same message in the function
  at different points.
