This adds support to dsymutil for linking remark files and placing them
in the final .dSYM bundle.
The result will be placed in:
* a.out.dSYM/Contents/Resources/Remarks/a.out
or
* a.out.dSYM/Contents/Resources/Remarks/a.out-<arch> for universal binaries
When multi-threaded, this runs a third thread which loops over all the
object files and parses remarks as it finds __remarks sections.
Testing this involves running dsymutil on pre-built binaries and object
files, then running llvm-bcanalyzer on the final result to check for
remarks.

When a Swift module built with debug info imports a library without
debug info from a textual interface, the textual interface is
necessary to reconstruct types defined in the library's interface. By
recording the Swift interface files in DWARF dsymutil can collect them
and LLDB can find them.
This patch teaches dsymutil to look for DW_TAG_imported_modules and
records all references to parseable Swift ingterfrace files and copies
them to
a.out.dSYM/Contents/Resources/<Arch>/<ModuleName>.swiftinterface

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

The unobufscation support for BCSymbolMaps was the last piece of code
that hasn't been upstreamed yet. This patch contains a reworked version
of the existing code and relevant tests.

This patch add support for emitting DWARF5 accelerator tables
(.debug_names) from dsymutil. Just as with the Apple style accelerator
tables, it's possible to update existing dSYMs. This patch includes a
test that show how you can convert back and forth between the two types.
If no kind of table is specified, dsymutil will default to generating
Apple-style accelerator tables whenever it finds those in its input. The
same is true when there are no accelerator tables at all. Finally, in
the remaining case, where there's at least one DWARF v5 table and no
Apple ones, the output will contains a DWARF accelerator tables
(.debug_names).

When implementing the DWARF accelerator tables in dsymutil I ran into an
assertion in the assembler. Debugging these kind of issues is a lot
easier when looking at the assembly instead of debugging the assembler
itself. Since it's only a matter of creating an AsmStreamer instead of a
MCObjectStreamer it made sense to turn this into a (hidden) dsymutil
feature.

This patch splits off some abstractions used by dsymutil's dwarf linker
and moves them into separate header and implementation files. This
almost halves the number of LOC in DwarfLinker.cpp and makes it a lot
easier to understand what functionality lives where.
