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.

Check that we warn about missing object files (this presumes that the files aren't
present in the machine's /Inputs/ folder, which should be a pretty safe bet).
