224dbf4aec Completely rewrite ELFObjectWriter::RecordRelocation.
I started trying to fix a small issue, but this code has seen a small fix too
many.

The old code was fairly convoluted. Some of the issues it had:

* It failed to check if a symbol difference was in the some section when
  converting a relocation to pcrel.
* It failed to check if the relocation was already pcrel.
* The pcrel value computation was wrong in some cases (relocation-pc.s)
* It was missing quiet a few cases where it should not convert symbol
  relocations to section relocations, leaving the backends to patch it up.
* It would not propagate the fact that it had changed a relocation to pcrel,
  requiring a quiet nasty work around in ARM.
* It was missing comments.

e8068692f9 [mips] Set HWEncoding field of registers. Use delete function
getMipsRegisterNumbering and use MCRegisterInfo::getEncodingValue instead.

3faac0a78c Add support for local dynamic TLS model in LowerGlobalTLSAddress. Direct object
emission is not supported yet, but a patch that adds the support should follow
soon.

47b92f3d83 Mips MC object code emission improvements:
"With this patch we can now generate runnable Mips code through LLVM
direct object emission. We have run numerous simple programs, both C
and C++ and with -O0 and -O3 from the output. The code is not production
ready, but quite useful for experimentation." Patch and message by
Jack Carter
