Summary:
Continuing from D77285, the external interfaces implemented by
`ELFDump.cpp` are now declared in `ELFDump.h` and moved into the
`llvm::objdump` namespace. Externs defined in `ELFDump.cpp` that are
unreferenced externally are also made static.

Summary:
This patch moves the forward declarations of command-line `cl::*`
externs in `MachODump.cpp` and `llvm-objdump.cpp` into the headers
corresponding to the file that defines the variable. At the same time,
these externs are moved into the `llvm::objdump` namespace. The externs
that are not referenced outside their defining translation unit are made
static.
This does not factor out uses of the Mach-O options from
`llvm-objdump.cpp`.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
We have a bug currently: printed tag names might overlap the
value column. It happens for MIPS now.
This patch adds a logic to calculate the size of indentation on fly
to fix such issues.

The PT_GNU_PROPERTY is generated by a linker to describe the
.note.gnu.property section. The Linux kernel uses this program header to
locate the .note.gnu.property section.
It is described in "The Linux gABI extension"
Include support for llvm-readelf, llvm-readobj and the yaml reader and
writers.

Summary: Matches GNU objdump. Makes debugging easier for me as I'm working out addresses from symbol+addend, so it would be good to be calculating in a single format.

The error reporting function are not consistent.
Before this change:
* They had inconsistent naming (e.g. 'error' vs 'report_error').
* Some of them reported the object name, others - dont.
* Some of them accepted the case when there was no error. (i.e. error code or Error had a success value).
This patch tries to cleanup it a bit.
It also renames report_error -> reportError, report_warning -> reportWarning
and removes a full stop from messages.

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?

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.

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.

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.

According to `MaskRay`, use `auto` for type inference, according to coding standards.
Delete some comments, because these comments can be easily inferred from codes.

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.

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.

* ELFTypes.h contains template magic for defining types based on endianess, size, and alignment.
* 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.
llvm-svn: 188022
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.
