c++: parameter pack inside static_assert [PR99893]
Here, we're not finding the parameter pack inside the static_assert because
STATIC_ASSERT trees are tcc_exceptional, and we weren't explicitly walking
them in cp_walk_subtrees.
PR c++/99893
gcc/cp/ChangeLog:
* tree.c (cp_walk_subtrees) <case STATIC_ASSERT>: New case.
gcc/testsuite/ChangeLog:
* g++.dg/cpp0x/static_assert17.C: New test.
