Log Message:
-----------
[WASM] Default-initialized fields of WASM GC struct should use Const32 if
appropriate for storage type
https://bugs.webkit.org/show_bug.cgi?id=283941
rdar://140773922
Reviewed by Yusuke Suzuki and Keith Miller.
Generates a Const32Value in OMG instead of a Const64Value when
zero-initializing fields in struct.new_default when the field
storage types are 32-bit or smaller. This satisfies the B3
validator which expects an Int32 input for Stores of 32 bits or
smaller.
