Cleanup: Set-up to print string constants.
If a SUBPIECE refers to a global symbol, the output of the SUBPIECE is a (char *), and the address is read-only, then get rid of the SUBPIECE in favor of printing a constant string.
Attempt to apply this Rule.
This method contains the main logic for applying the Rule. It must use a given PcodeOp as the point at which the Rule applies. If it does apply, changes are made directly to the function and 1 (non-zero) is returned, otherwise 0 is returned.
