c++: Fix bogus -Wparentheses warning with fold-expression [PR94505]
We issue bogus -Wparentheses warnings (3 of them!) for this fold expression:
((B && true) || ...)
Firstly, issuing a warning for a compiler-generated expression is wrong
and secondly, B && true must be wrapped in ( ) otherwise you'll get
error: binary expression in operand of fold-expression.
PR c++/94505 - bogus -Wparentheses warning with fold-expression.
* pt.c (fold_expression): Add warning_sentinel for -Wparentheses
before calling build_x_binary_op.
* g++.dg/cpp1z/fold11.C: New test.
