      [wasm-gc] Preparation for rtt global initializers · 8b9c2ac3
      Manos Koukoutos authored 
      Motivation: With rtt.sub now allowed in constant expressions, we have
to generalize WasmInitExpr to be able to handle expressions with
operands. This is the second CL that prepares the ground for this
change.

Changes:
- Remove the error from read-value-type when reading a generic rtt.
- Add validation for HeapTypeImmediate in ModuleDecoder. Use it to
  validate null constants immediates, which was missing. Add tests.
- Change ValueType::name to print rtt depths as integers.
- Move global initializer building in wasm-module-builder to its own
  function.

      [wasm-gc] Refactoring in preparation of generalizing WasmInitExpr · 01e59c4b
      Manos Koukoutos authored 
      Motivation: With rtt.sub now allowed in constant expressions, we have
to generalize WasmInitExpr to be able to handle expressions with
operands. This CL prepares the ground for this change and adds no
functionality.

Changes:
- ValueType::heap_representation and HeapType::representation now
  return HeapType::Representation.
- Add ValueType::is_rtt().
- WasmInitExpr:
  - Make kind private. Rename val -> operator, make it private. Add
    accessors.
  - Rename kGlobalIndex -> kGlobalGet.
  - Squash global_index and function_index into index.
  - Add heap_type Immediate. Use it for RefNullConst. TypeOf in
    module-decoder.cc can now fully determine the type of a
    WasmInitExpr.
  - Add class constructors/static method constructors for each Operator
    kind.
  - Delete copy constructor. WasmInitExpr will use std::unique_ptr for
    its operands.
- consume_init_expr now uses a stack.
- A few minor improvements.
