Joe Abbey 15d9834df9 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"

Rafael Espindola cdb9a538d6 Add support for .cfi_register now that it is easy to extent the representation

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 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.
