Update comments to operator_check
Commit Message
Hello,
I happen to read the code and find the comments to operator_check are
incorrect. This patch is to fix the comments per my understanding.
The comments and field operator_check was added by this patch
https://sourceware.org/ml/gdb-patches/2010-04/msg00556.html
but the inconsistency between code and comments wasn't pointed out during
the review.

* parser-defs.h (struct exp_descriptor) <operator_check>: Update
comments.
* parse.c (exp_iterate): Update comments.

Yeah, IIUC, that code was originally based on:
https://sourceware.org/ml/gdb-patches/2009-07/msg00054.html
