Now that almost all functionality of Apple's dsymutil has been
upstreamed, the open source variant can be used as a drop in
replacement. Hence we feel it's no longer necessary to have the llvm
prefix.

llvm-dsymutil was misinterpreting the value of common symbols as their
address when it actually contains their size. This didn't impact
llvm-dsymutil's ability to link the debug information for common symbols
because these are always found by name and not by address. Things could
however go wrong when the size of a common object matched the object
file address of another symbol. Depending on the link order of the symbols
the common object might incorrectly evict this other object from the
address to symbol mapping, and then link the evicted symbol with a wrong
binary address.
Use the new ability to have symbols without an object file address to fix
this.

llvm-dsymutil needs to emit dSYM companion bundles. These are binary files
that replicate some of the orignal binary file properties (sections and
symbols). To get acces to these properties, pass the binary path in the
debug map.

The dsymutil-classic -v option dumps the tool version rather than
putting it in verbose mode. Rename -v to -verbose and update the
tests that use it (in the process removing it from a few tests that
didn't require it anymore since the -dump-debug-map option was
introduced).
A followup commit will reintroduce the -v option that dumps the
version.

MachOObjectFile offers a method for detecting the correct triple, use
it instead of the previous approximation. This doesn't matter right
now, but it will become important for mach-o universal (fat) binaries.

The debug map contains the timestamp of the object files in references.
We do not check these in the general case, but it's really useful if
you have archives where different versions of an object file have been
appended. This allows llvm-dsymutil to find the right one.

The main use of the YAML debug map format is for testing inside LLVM. If we have IR
files in the tests used to generate object files, then we obviously don't know the
addresses of the symbols inside the object files beforehand.
This change lets the YAML import lookup the addresses in the object files and rewrite
them. This will allow to have test that really don't need any binary input.
