Jonas Devlieghere b43dfaa6c0 [Dsymutil] Remove redundant argument (NFC)
The dwarf streamer already holds a copy of the link options, so there's
no need to pass them as an argument.

Chandler Carruth 2946cd7010 Update the file headers across all of the LLVM projects in the monorepo
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.

Jonas Devlieghere 91b43adb69 [dsymutil] Upstream unobfuscation logic.
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.

Wolfgang Pieb f39a9bbe72 [DWARF] Revert r345546: Refactor range list extraction and dumping
This patch caused some internal tests to break which are being investigated.

Wolfgang Pieb fb6cffca09 [DWARF][NFC] Refactor range list extraction and dumping
The purpose of this patch is twofold: 
- Fold pre-DWARF v5 functionality into v5 to eliminate the need for 2 different 
  versions of range list handling. We get rid of DWARFDebugRangelist{.cpp,.h}.
- Templatize the handling of range list tables so that location list handling
  can take advantage of it as well. Location list and range list tables have the 
  same basic layout.

A non-NFC version of this patch was previously submitted with r342218, but it caused
errors with some TSan tests. This patch has no functional changes. The difference to
the non-NFC patch is that there are no changes to rangelist dumping in this patch.

Alexander Kornienko e74e0f11d1 Revert "[DWARF] reposting r342048, which was reverted in r342056 due to buildbot errors. Adjusted 2 test cases for ARM and darwin and fixed a bug with the original change in dsymutil."
This reverts commit r342218. Due to a number of failures under TSAN. An isolated
test case is being worked on.

Wolfgang Pieb 3a8781cf6c [DWARF] Refactoring range list dumping to fold DWARF v4 functionality into v5 handling
Eliminating some duplication of rangelist dumping code at the expense of
some version-dependent code in dump and extract routines.

Argyrios Kyrtzidis c30340b207 Add header guards to some headers that are missing them
Also adjust some of dsymutil's headers to put the header guards at the top,
otherwise the compiler will not recognize them as header guards.

Jonas Devlieghere 743d351120 [dsymutil] Add support for generating DWARF5 accelerator tables.
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).

Jonas Devlieghere 82dee6aca8 [dsymutil] Add support for outputting assembly
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.

Jonas Devlieghere c0fb4b6b88 [dsymutil] Move abstractions into separate files (NFC)
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.
