We have been using ld64's `-all_load` as the mac equivalent to
`--whole-archive`, but `-force_load` does something closer to what we want.
From the ld64 man page:
```
-all_load
Loads all members of static archive libraries.
-force_load path_to_archive
Loads all members of the specified static archive library. Note:
-all_load forces all members of all archives to be loaded. This
option allows you to target a specific archive.
```
When we link `libjulia-internal.dylib` and `libjulia-codegen.dylib` with
`-all_load`, we pull in more of the static LLVM support libraries than we need.
Before:
```
5.1M usr/lib/libjulia-internal.1.14.0.dylib
2.1M usr/lib/libjulia-codegen.1.14.0.dylib
```
After:
```
3.8M usr/lib/libjulia-internal.1.14.0.dylib
2.1M usr/lib/libjulia-codegen.1.14.0.dylib
```
