c++: std::variant slow to compile [PR109678]
Here, when dealing with a class with a complex subobject structure, we would
try and fail to find the relevant FIELD_DECL for an empty base before giving
up. And we would do this at each level, in a combinatorially problematic
way. Instead, we should check for an empty base first.
PR c++/109678
gcc/cp/ChangeLog:
* constexpr.cc (cxx_fold_indirect_ref_1): Handle empty base first.
gcc/testsuite/ChangeLog:
* g++.dg/cpp1z/variant1.C: New test.
