00e08fcaa0 Canonicalize header guards into a common format.
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)

Changes made by clang-tidy with minor tweaks.

740a75968a [DWARF parser] Fix broken address ranges construction.
Previous algorithm for constructing [Address ranges]->[Compile Units]
mapping was wrong. It somewhat relied on the assumption that address ranges
for different compile units may not overlap. It is not so.
For example, two compile units may contain the definition of the same
linkonce_odr function. These definitions will be merged at link-time,
resulting in equivalent .debug_ranges entries for both these units

Instead of sorting and merging original address ranges (from .debug_ranges
and .debug_aranges), implement a different approach: save endpoints
of all ranges, and then use a sweep-line approach to construct
the desired mapping. If we find that certain address maps to
several compilation units, we just pick any of them.

63a450a313 [DebugInfo] Generate address ranges for compile units even if .debug_aranges is present: it is often the case that .debug_aranges section contains ranges only for a small subset of compile units. Test cases will be added in separate commits.

10df80692c DWARF: Generate the address lookup table from the DIE tree if .debug_aranges is not available.
Ported from LLDB.

358f4fd9ee DWARF: Port support for parsing .debug_aranges section from LLDB and wire it up to llvm-dwarfdump.
This is only one half of it, the part that caches address ranges from the DIEs when .debug_aranges is
not available will be ported soon.
