61bdb20713 Removing SUPPORTS_COVERED_SWITCH_DEFAULT_FLAG 
Adding CXX_SUPPORTS_COVERED_SWITCH_DEFAULT_FLAG
       C_SUPPORTS_COVERED_SWITCH_DEFAULT_FLAG

This is to handle the wackiness on a Mac host where cmake detects:

CMAKE_CXX_COMPILER == "/usr/bin/c++"
CMAKE_C_COMPILER == "/usr/bin/gcc"

81ee486113 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.

349eb891a6 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.

0291ef94b9 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.

edc8307796 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.

0c5276155d 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.
