* Code: Generic 32-bit static field "get" operation. Uses no substitutions.
* For: sget-boolean, sget-byte, sget-char, sget-object, sget, sget-short
* Description: Perform the identified object static field operation
* with the identified static field; load the field value
* into the value register.
* Format: AA|op BBBB (21c)
* Syntax: op vAA, string@BBBB
