* cp-demangle.c (d_make_function_param): new fn.
(cplus_demangle_mangled_name): Work around abi v2 bug.
(d_expr_primary): Likewise.
(cplus_demangle_operators): Add alignof ops.
(d_expression): Handle function parameters and conversions
with other than 1 operand.
(d_print_comp): Handle function parameters. Fix bug with
function used in type of function.
* testsuite/demangle-expected: Upate tests.
