negDelta32 is only ever implicitly generated as the FDE->CIE reference.
We therefore don't emit a relocation for it in the object file in -r mode.
The value we write in to the FDE location therefore needs to point to the
final target address of the CIE, and not the inAtomAddress as it was currently
doing.

We used to parse the LLVM options in Driver::link. However, that is
after parse() where we load files. By moving the LLVM option handling
earlier, we can add DEBUG() to code such as MachONormalizedFileToAtoms.cpp
and have it enabled correctly by '-mllvm --debug'.

We had some DEBUG prints these passes, but add more so that its clear where we are dumping
things, and what state we are in when we do so.
I'll be adding more and more DEBUG printing to try make it easier to observe whats going on
without having to attach a debugger.

The delta64 relocation is represented as the pair ARM64_RELOC_SUBTRACTOR and ARM64_RELOC_UNSIGNED.
Those should always have the same offset, so this adds a check and tests to ensure this is the case.
Also updated the error printing in this case to shows both relocs when erroring on pair.

table.
The first entry in the MachO symbol table is always the empty string: make sure
we reserve space for it, or we will overflow the symbol table by one byte.
No test case - this manifests as an occasional memory error. In the near future
I hope to set up a bot building and runnnig LLD with sanitizers - that should
catch future instances of this issue.

The gcc_except_tab was generating these references to point to the typeinfo in the data section.
gcc_except_tab also had the DW_EH_PE_indirect flag set which means that at runtime we are going
to dereference this entry as if it is in the GOT.

MachODefinedCustomSectionAtom.
The section names for these atoms are initialized from temporaries (e.g.
segName + "/" + sectName), so we can't use StringRef here.

GNU linkers accept both variants and at least for MIPS target gcc passes
joined variant of the '-m' option.

This is a basic initial implementation of the -flat_namespace and
-undefined options for LLD-darwin. It ignores several subtlties,
but the result is close enough that we can now link LLVM (but not
clang) on Darwin and pass all regression tests.

Now it is possible to have mips-linux-gnu-ld executable and link MIPS 64-bit
little-endian binaries providing -melf64ltsmip command line argument.

This is a basic implementation that allows lld to emit binaries
consumable by the HSA runtime.
