LOG: [lld-macho] Remove old macho darwin lld
During the llvm round table it was generally agreed that the newer macho
lld implementation is feature complete enough to replace the old
implementation entirely. This will reduce confusion for new users who
aren't aware of the history.

-/// This linker pass transforms all GOT kind references to real references.
-/// That is, in assembly you can write something like:
-/// movq foo at GOTPCREL(%rip), %rax
-/// which means you want to load a pointer to "foo" out of the GOT (global
-/// Offsets Table). In the object file, the Atom containing this instruction
-/// has a Reference whose target is an Atom named "foo" and the Reference
-/// kind is a GOT load. The linker needs to instantiate a pointer sized
-/// GOT entry. This is done be creating a GOT Atom to represent that pointer
-/// sized data in this pass, and altering the Atom graph so the Reference now
-/// points to the GOT Atom entry (corresponding to "foo") and changing the
-/// Reference Kind to reflect it is now pointing to a GOT entry (rather
-/// then needing a GOT entry).
-///
-/// There is one optimization the linker can do here. If the target of the GOT
-/// is in the same linkage unit and does not need to be interposable, and
-/// the GOT use is just a load (not some other operation), this pass can
-/// transform that load into an LEA (add). This optimizes away one memory load
-/// which at runtime that could stall the pipeline. This optimization only
-/// works for architectures in which a (GOT) load instruction can be change to
-/// an LEA instruction that is the same size. The method isGOTAccess() should
-/// only return true for "canBypassGOT" if this optimization is supported.

-// This linker pass updates branch-sites whose target is a
diff erent mode
-// (thumb vs arm).
-//
-// Arm code has two instruction encodings thumb and arm. When branching from
-// one code encoding to another, you need to use an instruction that switches
-// the instruction mode. Usually the transition only happens at call sites, and
-// the linker can transform a BL instruction in BLX (or vice versa). But if the
-// compiler did a tail call optimization and a function ends with a branch (not
-// branch and link), there is no pc-rel BX instruction.
-//
-// The ShimPass looks for pc-rel B instructions that will need to switch mode.
-// For those cases it synthesizes a shim which does the transition, then
-// modifies the original atom with the B instruction to target to the shim atom.
