c++: Quash bogus -Wunused-value with new [PR107797]
We shouldn't emit "right operand of comma operator has no effect"
when that comma operator was created by the compiler for "new int{}".
convert_to_void/COMPOUND_EXPR already checks warning_suppressed_p so
we can just suppress -Wunused-value.
PR c++/107797
gcc/cp/ChangeLog:
* cvt.cc (ocp_convert): copy_warning when creating a new
COMPOUND_EXPR.
* init.cc (build_new_1): Suppress -Wunused-value on
compiler-generated COMPOUND_EXPRs.
gcc/testsuite/ChangeLog:
* g++.dg/warn/Wunused-value-1.C: New test.
