CallExpr - Represents a function call (C99 6.5.2.2, C++ [expr.call]).
CallExpr itself represents a normal function call, e.g., "f(x, 2)", while its subclasses may represent alternative syntax that (semantically) results in a function call. For example, CXXOperatorCallExpr is a subclass for overloaded operator calls that use operator syntax, e.g., "str1 + str2" to resolve to a function call.

Create a call expression.
Fn is the callee expression, Args is the argument array, Ty is the type of the call expression (which is not the return type in general), VK is the value kind of the call expression (lvalue, rvalue, ...), and RParenLoc is the location of the right parenthese in the call expression. MinNumArgs specifies the minimum number of arguments. The actual number of arguments will be the greater of Args.size() and MinNumArgs. This is used in a few places to allocate enough storage for the default arguments. UsesADL specifies whether the callee was found through argument-dependent lookup.
Note that you can use CreateTemporary if you need a temporary call expression on the stack.

Reduce the number of arguments in this call expression.
This is used for example during error recovery to drop extra arguments. There is no way to perform the opposite because: 1.) We don't track how much storage we have for the argument array 2.) This would potentially require growing the argument array, something we cannot support since the arguments are stored in a trailing array.

Return the size in bytes needed for the trailing objects.
Used by the derived classes to allocate the right amount of storage.
