c++: Fix tsubsting CLASS_PLACEHOLDER_TEMPLATE [PR95434]
Here, during partial instantiation of the generic lambda, we do
tsubst_copy on the CLASS_PLACEHOLDER_TEMPLATE for U{0} which yields a
(level-lowered) TEMPLATE_TEMPLATE_PARM rather than the corresponding
TEMPLATE_DECL. This later confuses do_class_deduction which expects
that a CLASS_PLACEHOLDER_TEMPLATE is always a TEMPLATE_DECL.
gcc/cp/ChangeLog:
PR c++/95434
* pt.c (tsubst) <case TEMPLATE_TYPE_PARM>: If tsubsting
CLASS_PLACEHOLDER_TEMPLATE yields a TEMPLATE_TEMPLATE_PARM,
adjust to its TEMPLATE_TEMPLATE_PARM_TEMPLATE_DECL.
gcc/testsuite/ChangeLog:
PR c++/95434
* g++.dg/cpp2a/lambda-generic9.C: New test.
