Added

• f32.hypot and f64.hypot are now much more numerically exact in
  the interpreter.

• Generated code now contains a header with information about the
  version of Futhark used (and maybe more information in the
  future).

• Testing/benchmarking with large input data (including randomly
  generated data) is much faster, as each file is now only read
  once.

• Test programs may now use arbitrary FutharkScript expressions to
  produce test input, in particular expressions that produce opaque
  values. This affects both testing, benchmarking, and autotuning.

• Compilation is about 10% faster, especially for large programs.

Fixed

• futhark repl had trouble with declarations that produced unknown
  sizes (#1347).

• Entry points can now have same name as (undocumented!) compiler intrinsics.

• FutharkScript now detects too many arguments passed to functions.

• Sequentialisation bug (#1350).

• Missing causality check for index sections.

• futhark test now reports mismatches using proper indexes (#1356).

• Missing alias checking in fusion could lead to compiler crash (#1358).

• The absolute value of NaN is no longer infinity in the interpreter (#1359).

• Proper detection of zero strides in compiler (#1360).

• Invalid memory accesses related to internal bookkeeping of bounds checking.
