Sync libiberty with GCC.
libiberty/ChangeLog: * d-demangle.c (dlang_call_convention): Handle extern Objective-C function calling convention. (dlang_call_convention_p): Likewise. (dlang_type): Likewise. * testsuite/d-demangle-expected: Add coverage tests. * d-demangle.c (dlang_function_args): Append ',' for variadic functions only if parameters were seen before the elipsis symbol. * testsuite/d-demangle-expected: Add coverage test for parameter-less variadic functions. * d-demangle.c (dlang_type): Handle function types only in the context of seeing a pointer type symbol. * testsuite/d-demangle-expected: Update function pointer tests.
