  • slice syntax is a[start?:count?] or a[start?:count?:step]
  • designated array initializers accept a range index
  • array initialisation checker updated for designated ranges
  • bit selections are mutated during analysis as BitSelectionExpr

Compiler: add support for generalized slice syntax
e5a2855 
* parse slice syntax: a[start?:count?] or a[start?:count?:step],
  producing `ArraySelectionExpr` AST objects.
* `ArraySelectionExpr` with a builtin base object are changed to
  `BitSelectionExpr` objects at analysis time.
* removed bitoffset indexing object
* array slices are not supported in expressions yet
