description:
lint: remove comment from grammar rule type_direct_decl

The 'identifier' in type_direct_decl is necessary, as demonstrated in
the test d_typename_as_var.  Replacing T_NAME with 'identifier' in
notype_direct_decl would increase the shift/reduce conflicts by 6.  To
keep this number low, keep everything as-is.
