8258075: Use auto variable declarations for enum iteration

[iklam]

The pattern used in #1707

for (vmIntrinsicID index : EnumRange<vmIntrinsicID>{}) {
  nt[as_int(index)] = string;
}

can be further simplified to the following without loss of readability, since the type of index would obviously be the type enclosed by EnumRange<>

for (auto index : EnumRange<vmIntrinsicID>{}) {
  nt[as_int(index)] = string;
}

(as suggested by John Rose)
