Meador Inge 7415f8403d instcombine: Migrate ffs* optimizations 
This patch migrates the ffs* optimizations from the simplify-libcalls
pass into the instcombine library call simplifier.

Joe Abbey 2ad8df24ec Code Custodian: 
- Widespread trailing space removal
  - A dash of OCD spacing to block align enums
  - joined a line that probably needed 80 cols a while back

Rafael Espindola cdb9a538d6 Add support for .cfi_register now that it is easy to extent the representation 
to support it. Original patch with the parsing and plumbing by the PaX team and
Roman Divacky. I added the bits in MCDwarf.cpp and the test.

Benjamin Kramer 9bcb9226f6 libLTO: Add a utility method to initialize the disassemblers. 
Necessary to give disassembler users (like darwin's otool) a possibility to
dlopen libLTO and still initialize the required LLVM bits. This used to go
through libMCDisassembler but that's a gross layering violation, the MC layer
can't pull in functions from the targets. Adding a function to libLTO is a bit
of a hack but not worse than exposing other disassembler bits from libLTO.

Fixes PR14362.

Rafael Espindola cc0c74a76c Change the representation of MCCFIInstruction. 
We now store the Register and Offset directly. MachineLocation is gone (from
this file)!

Rafael Espindola 5dce65b21e Give each MCCFIInstruction its own opcode. 
This untangles the switch cases of the old Move and RelMove opcodes a bit
and makes it clear how to add new instructions.

Rafael Espindola 1c3086cc91 Refactor how MCCFIInstructions are created. 
Give MCCFIInstruction a single, private constructor and add helper static
methods that create each type of cfi instruction. This is is preparation
for changing its representation. The representation with a pair
MachineLocations older than MC and has been abused quiet a bit to support
more cfi instructions.

Preston Briggs 3ad394931d Corrects a problem where we reply exclusively of GEPs to drive 
analysis.  Better is to look for cases with useful GEPs and use them
when possible.  When a pair of useful GEPs is not available, use the
raw SCEVs directly. This approach supports better analysis of pointer
dereferencing.

In parallel, all the test cases are updated appropriately.
Cases where we have a store to *B++ can now be analyzed!

Jack Carter b05cb67b81 Mips direct object xgot support 
This patch provides support for the MIPS relocations:

    *)  R_MIPS_GOT_HI16
    *)  R_MIPS_GOT_LO16
    *)  R_MIPS_CALL_HI16
    *)  R_MIPS_CALL_LO16

These are used for large GOT instruction sequences.
