This models a one or multi-dimensional C/C++ array. The type implements the `ShapedTypeInterface` and prints similar to memref/tensor: ``` %arg0: !emitc.array<1xf32>, %arg1: !emitc.array<10x20x30xi32>, %arg2: !emitc.array<30x!emitc.ptr<i32>>, %arg3: !emitc.array<30x!emitc.opaque<"int">> ``` It can be translated to a C array type when used as function parameter or as `emitc.variable` type.
