Use deduction guides instead of helper functions.
The only non-automatic changes have been:
1. ArrayRef(some_uint8_pointer, 0) needs to be changed into ArrayRef(some_uint8_pointer, (size_t)0) to avoid an ambiguous call with ArrayRef((uint8_t*), (uint8_t*))
2. CVSymbol sym(makeArrayRef(symStorage)); needed to be rewritten as CVSymbol sym{ArrayRef(symStorage)}; otherwise the compiler is confused and thinks we have a (bad) function prototype. There was a few similar situation across the codebase.
3. ADL doesn't seem to work the same for deduction-guides and functions, so at some point the llvm namespace must be explicitly stated.
4. The "reference mode" of makeArrayRef(ArrayRef<T> &) that acts as no-op is not supported (a constructor cannot achieve that).
Per reviewers' comment, some useless makeArrayRef have been removed in the process.
This is a follow-up to https://reviews.llvm.org/D140896 that introduced
the deduction guides.

This avoids recomputing string length that is already known at compile time.
It has a slight impact on preprocessing / compile time, see

This a recommit of e953ae5bbc313fd0cc980ce021d487e5b5199ea4 and the subsequent fixes caa713559bd38f337d7d35de35686775e8fb5175 and 06b90e2e9c991e211fecc97948e533320a825470.
The above patchset caused some version of GCC to take eons to compile clang/lib/Basic/Targets/AArch64.cpp, as spotted in aa171833ab0017d9732e82b8682c9848ab25ff9e.
The fix is to make BuiltinInfo tables a compilation unit static variable, instead of a private static variable.

llvm-dwarutil.cpp redundantly calls to InitializeAllAsmParsers.
That call might be removed as well as dependency on ${LLVM_TARGETS_TO_BUILD}

Current DWARFLinker implementation does not support some debug sections
(mainly DWARF v5 sections). This patch adds diagnostic for such sections.
The warning would be displayed for critical(such that could not be removed)
sections and the source file would be skipped. Other unsupported sections
would be removed and warning message should be displayed. The zero exit
status would be returned for both cases.

llvm-dwarfutil - is a tool that is used for processing debug info(DWARF) located in built binary files to improve debug info quality, reduce debug info size. The patch currently implements smaller set of command-line options(comparing to the proposal):
```
./llvm-dwarfutil [options] <input file> <output file>
--garbage-collection Do garbage collection for debug info(default)
-j <value> Alias for --num-threads
--no-garbage-collection Don`t do garbage collection for debug info
--no-odr-deduplication Don`t do ODR deduplication for debug types
--no-odr Alias for --no-odr-deduplication
--no-separate-debug-file
Create single output file, containing debug tables(default)
--num-threads <threads> Number of available threads for multi-threaded execution. Defaults to the number of cores on the current machine
--odr-deduplication Do ODR deduplication for debug types(default)
--odr Alias for --odr-deduplication
--separate-debug-file Create two output files: file w/o debug tables and file with debug tables
--tombstone [bfd,maxpc,exec,universal]
Tombstone value used as a marker of invalid address(default: universal)
=bfd - Zero for all addresses and [1,1] for DWARF v4 (or less) address ranges and exec
=maxpc - Minus 1 for all addresses and minus 2 for DWARF v4 (or less) address ranges
=exec - Match with address ranges of executable sections
=universal - Both: bfd and maxpc
```
