* --dynamic-list has different semantics for executables and DSOs. Previously,
    mold implemented only the semantics for executables, causing issues with
    libraries such as musl that used this option. mold now handles the option for
    DSOs correctly. (da3f5dd)
  * Old object files often contain .ctors and .dtors sections, which hold function
    pointers for initializing and finalizing processes, respectively. Their roles
    have been superseded by .init_array and .fini_array on most targets. mold worked
    functioned correctly as long as input object files consistently use the old or
    the new sections. However, mixing object files that contain both types of
    initializers/finalizers resulted in some functions not being executed. This
    issue has been fixed. (3f88964)
  * --defsym can cause the linker to crash if a given symbol is not defined. The
    crash bug has been fixed. (ff3d54d)
  * [POWER10] On rare occasions, pointers statically initialized to functions could
    be left as null pointers. This bug has been fixed. (31c3b53)

Subject: [PATCH] [POWER10] Emit dynamic relocation for ifunc
Previously, we didn't emit a dynamic relocation for a statically-
initialized function pointer pointing to an ifunc on POWER10, e.g.
int fn() __attribute__((ifunc("resolve_fn")));
void *ptr = fn;
Fixes https://github.com/rui314/mold/issues/1142
