+Aggregate resource types with register annotations
+occupy the first register they specify and however many additional sequential registers
 the aggregate requires to assign a register to each of its elements that correspond to the given register type.
 Multiple register annotations can be placed on aggregates involving structs where each corresponds to a distinct
 register type that will apply to all the registers of that type in the aggregate.

 Resource types contained in structs are only allocated registers when they are explicitly used.
