[lld][MachO] Recognize __thread_bss sections as zero-fill and set all the

appropriate bits.
This fixes the remaining clang regression test failures when linking clang with

Verify that macho-o delta64 relocs have the same offset.
...
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.

[lld][MachO] Always reserve space for the empty string in the mach-o symbol
...
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.

Don't bypass the GOT for delta32toGOT references.
...
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.
