badb15e1da [llvm-objdump] Should print unknown d_tag in hex format
Summary:
Currently, `llvm-objdump` prints "unknown" instead of d_tag value in hex format. Because getDynamicTagAsString returns "unknown" rather than empty 
string.

ddb967d7a3 [llvm-objdump] Should print strings when dumping DT_RPATH, DT_RUNPATH, DT_SONAME, DT_AUXILIARY and DT_FILTER tags in dynamic section.
Summary:
Before:
```
Dynamic Section:
  NEEDED               libpthread.so.0
  ...
  NEEDED               ld-linux-x86-64.so.2
  RPATH                0x00000000001c2e61
```

After:
```
Dynamic Section:
  NEEDED               libpthread.so.0
  ...
  NEEDED               ld-linux-x86-64.so.2
  RPATH                $ORIGIN/../lib
```

Only a small problem here, I have no idea on choosing test case. I see there's a test 
file(test/tools/llvm-objdump/private-headers-dynamic-section.test). But it has no DT_RPATH and DT_RUNPATH tags. Shall I replace the ELF file in the 
Inputs dir by a new one?

4771873908 [llvm-objdump] - Print LMAs when dumping section headers.
When --section-headers is used, GNU objdump prints both LMA and VMA for sections.
llvm-objdump does not do that what makes it's output be slightly inconsistent.

Patch teaches llvm-objdump to print LMA/VMA for ELF file formats.
The behavior for other formats remains unchanged.

6b547686c5 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.

605942eacd [llvm-objdump] - Move getRelocationValueString and dependenices out of the llvm-objdump.cpp
getRelocationValueString is a dispatcher function that calls the
corresponding ELF/COFF/Wasm/MachO implementations
that currently live in the llvm-objdump.cpp file.

These implementations better be moved to ELFDump.cpp,
COFFDump.cpp and other corresponding files, to move platform specific
implementation out from the common logic.

The patch does that. Also, I had to move ToolSectionFilter helper
and SectionFilterIterator, SectionFilter to a header to make them
available across the objdump code.

26b584c691 Remove \brief commands from doxygen comments.
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

63830bcae9 [ELF] Convert ELF.h to Expected<T>.
This has two advantages:
1) We slowly move away from ErrorOr to the new handling interface,
in the hope of having an uniform error handling in LLVM, eventually.
2) We're starting to have *meaningful* error messages for invalid
object ELF files, rather than a generic "parse error". At some point
we should include also the offset to improve the quality of the
diagnostic.

* ELFFile.h defines the ELFFile class which provides low level ELF specific access.
* ELFObjectFile.h contains ELFObjectFile which uses ELFFile to implement the ObjectFile interface.

ac97f5ce48 [Object][ELF] Simplify ELFObjectFile by using ELFType.
This simplifies the usage and implementation of ELFObjectFile by using ELFType
to replace:

<endianness target_endianness, std::size_t max_alignment, bool is64Bits>

This does complicate the base ELF types as they must now use template template
parameters to partially specialize for the 32 and 64bit cases. However these
are only defined once.
