functionml_fatal_trap_invalid_list_linkage

__attribute__((cold, noreturn, always_inline))
static inline void ml_fatal_trap_invalid_list_linkage(unsigned long e)

Used for when `e` failed a linked list safe unlinking check. On optimized builds, `e`'s value will be in: - %rax for Intel - x8 for arm64 - r8 on armv7
