Merge pull request #1413 from hzeller:ir-fix-include

PiperOrigin-RevId: 634599228

Add support in VAST for various SystemVerilog constructs.

- Typedefs
- Enums
- Structs
- Arrays with a specified element type
- Arrays with an expression that is the max rather than the width
- Return statements
- More complete parameter and argument declarations
- Literals that explicitly declare width and signedness
- Power operator
- Remove the prohibition on DataType::Emit(), since it now needs to be emitted in contexts without an identifier.

Refine unconstrained calculation for small array indexes

If an array index is not large enough to address all possible array elements it is by definition constrained. Make RangeQueryEngine aware of this fact in ArrayUpdate.
