qbe: Remove unnecessary value copy for struct/union types

Previously, this was needed so that an aggregate type value was
updated to be an 'l' type value. However, since 5ff1d2fa the aggregate
type name is stored in a separate parameter in IARG/ICALL instructions,
so we can just re-use the same pointer value.
