gdb: Add new parser rule for structure field names
Introduces a new rule in c-exp.y for matching structure field names. This is a restructure in preparation for the next commit, this commit shouldn't result in any user visible changes. gdb/ChangeLog: * c-exp.y (field_name): New %token, and new rule. (exp): Replace uses of 'name' with 'field_name' where appropriate.
