Adrian Prantl 057d336c0d llvm-dwarfdump: Add support for -debug-info=<offset>.
This is the first of many commits that enable selectively dumping just
one record from the debug info.

This reapplies r313412 with some extra qualification to appease GCC and MSVC.

Jonas Devlieghere 27476ce24b [dwarfdump] Rename Brief to Verbose in DIDumpOptions
This patches renames "brief" to "verbose" in de DIDumpOptions and
inverts the logic to match the new behavior where brief is the default.
Changing the default value uncovered some bugs related to the
DIDumpOptions not being propagated and have been fixed as well.

Adrian Prantl 7bc1b28291 llvm-dwarfdump: Replace -debug-dump=sect option with individual options.
As discussed on llvm-dev in
http://lists.llvm.org/pipermail/llvm-dev/2017-September/117301.html
this changes the command line interface of llvm-dwarfdump to match the
one used by the dwarfdump utility shipping on macOS. In addition to
being shorter to type this format also has the advantage of allowing
more than one section to be specified at the same time.

In a nutshell, with this change

  $ llvm-dwarfdump --debug-dump=info
  $ llvm-dwarfdump --debug-dump=apple-objc

becomes

  $ dwarfdump --debug-info --apple-objc

Jonas Devlieghere 8ac8df03c1 [llvm-dwarfdump] Brief mode only dumps debug_info by default
This patch changes the default behavior in brief mode to only show the
debug_info section. This is undoubtedly the most popular and likely the
one you'd want in brief mode.

Non-brief mode behavior is not affected and still defaults to all.

SUMMARY

This patch adds a verification check on the abbreviation declarations in the .debug_abbrev section.
The check makes sure that no abbreviation declaration has more than one attributes with the same name.

Spyridoula Gravani f6bd788dda [DWARF] Modification of code for the verification of .debug_info section.
Summary:
This patch modifies the handleDebugInfo() function so that we verify the contents of each unit
in the .debug_info section only if its header has been successfully verified.

This change will allow for more/different verification checks depending on the type of the unit since from
dwarf5, the .debug_info section may consist of different types of units.

Spyridoula Gravani 890eedc4e4 [DWARF] Introduce verification for the unit header chain in .debug_info section to llvm-dwarfdump.
This patch adds verification checks for the unit header chain in the .debug_info section.
Specifically, for each unit in the .debug_info section, the verifier checks that:

The unit length is valid (i.e. the unit can actually fit in the .debug_info section)
The dwarf version of the unit is valid
The address size is valid (4 or 8)
The unit type (if the unit is in dwarf5) is valid
The debug_abbrev_offset is valid

Spyridoula Gravani 837c110cb1 [DWARF] Added verification checks for the .apple_names section.
This patch verifies the number of atoms, the validity of the form for each atom, as well as the validity of the
hashdata. For hashdata, we're verifying that the hashdata offset is correct and that the offset in the .debug_info for
each DIE in the hashdata is also valid.
