  Fix codegen for initialization of global atomics

This amends 2e275e24355cb224981f9beb2b026a3169fc7232. That commit added
a null to pointer cast kind when determining whether the expression can
be a valid constant initializer, but failed to update the constant
expression evaluator to perform the evaluation. This commit updates the
constant expression evaluator to handle that cast kind.
