26a45fe57e Revert "MC/MachO: Fix possible null pointer dereference." 
This reverts commit 110575.

Target.isAbsolute() is true if SD would be null.

5446bab8a5 The variable "Value" is carefully set to Layout.getSymbolAddress, 
but then not actually used - maybe a bug?  Remove the variable.

89a1d9036a MC/Mach-O/x86_64: Darwin's special "signed_N" relocation types should only be 
used to replace a normal relocation, not a reference to a GOT entry.

3c66c7a3c1 MC/Mach-O/x86_64: Add relocation support. 
- This is "extraordinarily" Darwin 'as' compatible. See the litany of FIXMEs littered about for more information.
 - There are a few cases which seem to clearly be 'as' bugs which I have left unsupported, and there is one cases where we diverge but should fix if it blocks diffing .o files (Darwin 'as' ends up widening a jump unnecessarily).
 - 403.gcc build, runs, and diffs equivalently to the 'as' built version now (using llvm-mc). However, it builds so slowly that I wouldn't recommend trying it quite yet. :)
