Frederic Riss c99ea20eda [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.

Frederic Riss b981832951 [dsymutil] Add a LinkOptions struct to pass to the DwarfLinker. NFC.
The only option we have to pass down currently is verbosity, but there
are more to come.

Frederic Riss 51bd34aa38 [dsymutil] Add -o option to select ouptut filename
We do not create the output file yet, so no means to test.

Chandler Carruth d9903888d9 [cleanup] Re-sort all the #include lines in LLVM using
utils/sort_includes.py.

I clearly haven't done this in a while, so more changed than usual. This
even uncovered a missing include from the InstrProf library that I've
added. No functionality changed here, just mechanical cleanup of the
include order.

Frederic Riss 231f714e54 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.
