[cgen] suggestion: improve error message

- Subject: [cgen] suggestion: improve error message
If you use the wrong operand in an insn, you get a vague "assert:
indx" error. This replaces it with a (hopefully) more instructive
message, hopefully allowing you to *find* the error.
* operand.scm (-anyof-merge-syntax): Print a more useful error
message.
