Zhou Sheng c1cf629e41 Fix a PassManager pointer use-after-free bug. 
The bug can be triggered when we require LoopInfo analysis ahead of DominatorTree construction in a Module Pass. The cause is that the LoopInfo analysis itself also invokes DominatorTree construction, therefore, when PassManager schedules LoopInfo, it will add DominatorTree first. Then after that, when the PassManger turns to schedule DominatorTree invoked by the above ModulePass, it finds there is already a DominatorTree, so it delete the redundant one. However, somehow it still try to access that pass pointer after free as code pasted below, which results in segment fault.

Joe Abbey 2ad8df24ec Code Custodian:

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.

Benjamin Kramer dd76a93af5 PPC: MCize most of the darwin PIC emission.

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.

Rafael Espindola b3b60570e3 Add a -disable-cfi option to llvm-mc. This is useful for debugging as 
it will expand any .cfi_* directives in the input assembly.

Unfortunately this cannot replace elf-dump in tests as the asm streamer
cannot relax the line advance opcodes.
