CHECK, CHECK_EQ etc., and NOTREACHED/NOTIMPLEMENTED have moved
to the much smaller headers check.h, check_op.h, and notreached.h,
respectively.
This CL updates .cc files to use those headers instead when
possible, with the purpose of saving compile time.

Disassembler (Win32 and ELF) uses reloc to find abs32 locations, which
are stored in (1) |abs32_locations_|. Later on, (1) is filtered to
generate (2) actual abs32 locations.
A patching failure case was discovered: Equivalence blocks must never
cut across reference boundaries. However, it turns out blocks generated
using (2) were subject to checks using (1), which triggers a failure
since (1) - (2) is nonempty.
One way for (1) != (2) to happen is from CURRENT_MODULE() usage, which
creates an abs32 reference outside a section. This results in an abs32
target whose RVA does not map to an offset using section data, and
gets rejected by filtering logic for (2).
Fix: Apply the filtering logic direcly to (1), so (1) == (2). Details:
* Add RemoveUntranslatableAbs32() (abs32_utils.h), which uses the
filtering logic for (2) to preemptively remove problematic RVAs
from (1), so |abs32_locations_| matches (2). Extensive unit tests
are added.
* DisassemblerWin32<Traits>::ParseAndStoreAbs32(): Initialize
|abs32_locations_| with 3 steps: Naive extraction from relocs,
RemoveUntranslatableAbs32(), and RemoveOverlappingAbs32Locations().
* DisassemblerElf<Traits>::GetAbs32FromRelocSections(): Do the same,
noting that ELF's image base is always 0.
Additional fixes:
* address_translator.h: kInvalidRva was -1, but it should be -2 to
better match kInvalidOffset.
* Abs32RvaExtractorWin32::Abs32RvaExtractorWin32: The lambda
|find_and_check| binds |addr|, which has been std::move()'ed.
Better to just bind |this| and use |addr_|.

Adds kVAWidth to Elf32Traits and use it in
DisassemblerElfIntel::MakeReferenceGroups as the width of
kReloc and kAbs32 reference types.

Creates Disassembler that recognises and parses ELF format. For now, it only supports Intel architeture. Support for Arm will be added in follow-up CLs.

With recent refactoring by etiennep@ marking high bits is no longer
required. This removes checks for existing high bits which were
previously filtered out to avoid conflicts with the marking system
used.

(Use "git log --follow" to see older revisions of files).
/components/ is the most logical place to put Zucchini, which only
depends on /base and /testing/gtest. This move also enables Zucchini to
be used by the Component Updater. Details:
- Move all files; run the following to change deps and guards:
sed 's/chrome\/installer/components/' *.cc *.h -i
sed 's/CHROME_INSTALLER/COMPONENTS/' *.cc *.h -i
- Sorting works out pretty well!
- Change all 'chrome/installer/zucchini' to 'components/zucchini'
throughout other parts of the repo; sort if necessary.
- Fix 6 'git cl lint' errors.
- Change 1 Bind() usage to BindRepeated().
- Update OWNER.
