Summary: Ana Pazos reported a bug where we were not checking that an APInt would fit into 64-bits before calling `getSExtValue()`. This caused asserts when compiling large constants, such as i128s, as happens when compiling compiler-rt. This patch adds a testcase and makes the callback less error-prone.
