6d500da3cc Revert "[ELF] Order DT_NEEDED entries by command line order." 
This reverts commit r204291 because it broke buildbots.

e29132d427 [Mips] Fix handling of R_MIPS_GOT16 relocation and building local part 
of GOT.
 * Read addend for R_MIPS_GOT16 relocation.
 * Put only high 16 bits of symbol + addend into GOT entries for
   locally visible symbols.

49fa6a41f4 [Mips] Factor out the code creates GOT entry atoms into the two 
functions. The first one is for local GOT entries. The second one is for
global GOT entries.

13c70b6d4b Replace OwningPtr with std::unique_ptr. 
This results in some simplifications to the code where an OwningPtr had to
be used with the previous api and then ownership moved to a unique_ptr for
the rest of lld.

b9d84f4d14 [lld] Include reference kind in cycle detector debug output
