In Mach-O object files, there are two kinds of relocations: "external" relocation, which targets a symbol, and "non-external" relocation, which targets a section. For targeting symbols not in the current object, we must use symbol-targeted relocations. For targeting symbols defined in the current object, for some relocation types, both kinds can be used. We currently use section-targeted relocations for R_ADDR targeting locally defined symbols. Modern Apple toolchain seems to prefer symbol-targeted relocations. Also, Apple's new linker, ld-prime, seems to not handle section- targeted relocations well in some cases. So this CL switches to always generate symbol-targeted relocations. This also simplifies the code. One exception is that DWARF tools seem to handle only section- targeted relocations. So generate those in DWARF sections. This CL supersedes CL 502616. Fixes #60694. For #61229.
