c++: Check if allocation functions are xobj members [PR114078]
A class allocation member function is implicitly 'static' by [class.free] p3, so cannot have an explicit object parameter. PR c++/114078 gcc/cp/ChangeLog: * decl.cc (grokdeclarator): Check allocation functions for xobj parameters. gcc/testsuite/ChangeLog: * g++.dg/cpp23/explicit-obj-ops-alloc.C: New test.
