Initial dsymutil tool commit. The goal of this tool is to replicate Darwin's dsymutil functionality based on LLVM. dsymutil is a DWARF linker. Darwin's linker (ld64) does not link the debug information, it leaves it in the object files in relocatable form, but embbeds a `debug map` into the executable that describes where to find the debug information and how to relocate it. When releasing/archiving a binary, dsymutil is called to link all the DWARF information into a `dsym bundle` that can distributed/stored along with the binary. With this commit, the LLVM based dsymutil is just able to parse the STABS debug maps embedded by ld64 in linked binaries (and not all of them, for example archives aren't supported yet). Note that the tool directory is called dsymutil, but the executable is currently called llvm-dsymutil. This discrepancy will disappear once the tool will be feature complete. At this point the executable will be renamed to dsymutil, but until then you do not want it to override the system one.

[dsymutil] Add the DwarfStreamer class. This class is responsible for getting the linked data to the disk in the appropriate form. Today it it an empty shell that just instantiates an MC layer. As we do not put anything in the resulting file yet, we just check it has the right architecture (and check that -o does the right thing). To be able to create all the components, this commit adds a few dependencies to llvm-dsymutil, namely all-targets, MC and AsmPrinter. Also add a -no-output option, so that tests that do not need the binary result can continue to run even if they do not have the required target linked in. llvm-svn: 230824 2015-02-28 01:29:11 +01:00			`required_libraries = AsmPrinter DebugInfoDWARF MC Object Support all-targets`
