* cp-demangle.c (d_print_comp): Suppress argument list for function
references by the '&' unary operator. Keep also already processed
variant without the argument list. Suppress argument list types for
function call used in an expression.
* testsuite/demangle-expected: Fix excessive argument list types in
`test for typed function in decltype'. New testcase for no argument
list types printed. 3 new testcases for function references by the
'&' unary operator..
