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.
