0.17.2

Added

• Obscure loop optimisation (#1110).

• Faster matrix transposition in C backend.

• Library code generated with CUDA backend can now be called from
  multiple threads.

• Better optimisation of concatenations of array literals and
  replicates.

• Array creation C API functions now accept const pointers.

• Arrays can now be indexed (but not sliced) with any signed integer
  type (#1122).

• Added --list-devices command to OpenCL binaries (#1131)

• Added --help command to C, CUDA and OpenCL binaries (#1131)

Removed

• The integer modules no longer contain iota and replicate
  functions. The top-level ones still exist.

• The size module type has been removed from the prelude.

Changed

• Range literals may no longer be produced from unsigned integers.

Fixed

• Entry points with names that are not valid C (or Python)
  identifiers are now pointed out as problematic, rather than
  generating invalid C code.

• Exotic tiling bug (#1112).

• Missing synchronisation for in-place updates at group level.

• Fixed (in a hacky way) an issue where reduce_by_index would use
  too much local memory on AMD GPUs when using the OpenCL backend.
