Lifted adjustFixupValue() from Darwin for sharing w ELF.
Test added

  refactor ELFObjectWriter::RecordRelocation more.
  Possibly share more code with Darwin?
  Lots more relocations...

legalization time. Since at legalization time there is no mapping from
SDNode back to the corresponding LLVM instruction and the return
SDNode is target specific, this requires a target hook to check for
eligibility. Only x86 and ARM support this form of sibcall optimization
right now.

* Encode the Thumb1 load and store instructions. This involved a bit of

Thumb2 encoding to share code with the ARM encoding, which gets use fixup support for free.
It also allows us to fold away at least one codegen-only pattern.
