  [Clang][ExprConst] Drop PRValue for nothrow new (#226753)

A user defined operator new can accept prvalue for nothrow. However, it
should not be a ConstExpr. Early returns by
isUsableAsGlobalAllocationFunctionInConstantEvaluation instead of doing
LValue evaluation.
Also, move CheckPlacement new logic into new OpCode. This decouples
checking from Interp.cpp to Compiler.cpp.
