(d_print_init): Initialize it.
(d_print_comp_inner) <DEMANGLE_COMPONENT_TEMPLATE_PARAM>: Check
is_lambda_arg for auto.
<DEMANGLE_COMPONENT_REFERENCE,
DEMANGLE_COMPONENT_RVALUE_REFERENCE>: Skip smashing check when
is_lambda_arg.
<DEMANGLE_COMPONENT_LAMBDA>: Increment is_lambda_arg around arg
printing.
* testsuite/demangle-expected: Add lambda auto mangling cases.
gcc/testsuite/
PR c++/78252
