The function `handleDebugValue` has custom logic to handle certain kinds constants, namely integers, floats and null pointers. However, it does not handle constant pointers created from IntToPtr ConstantExpressions. This patch addresses the issue by replacing the Constant with its integer operand. A similar bug was addressed for GlobalISel in D130642. Reviewed By: aprantl, #debug-info Differential Revision: https://reviews.llvm.org/D130908
