Most modern tools only accept two-dash long options. Remove one-dash
long options which are not recognized by GNU style `getopt_long`.
This ensures long options cannot collide with grouped short options.
Note: llvm-symbolizer has `-demangle={true,false}` for pprof compatibility
(for a while). They are kept.

In the help output of other tools and in the symbolizer command guide,
Mach-O specific options are in their own section. This change fixes the
symbolizer help output to be consistent.

llvm-symbolizer used to use the DIA SDK for symbolization on
Windows; this patch switches to using native symbolization, which was
implemented recently.
Users can still make the symbolizer use DIA by adding the `-dia` flag
in the LLVM_SYMBOLIZER_OPTS environment variable.

The switch from llvm::cl to OptTable (D83530) dropped --version, which
is needed by some users.
This patch also adds a -v alias, which is available in GNU addr2line.
The version dumping is similar to llvm-objcopy --version (exotic):
```
llvm-symbolizer
LLVM (http://llvm.org/):
LLVM version 12.0.0git
Optimized build with assertions.
Default target: x86_64-unknown-linux-gnu
Host CPU: skylake-avx512

D83530 removed --inlining={true,false} which were used by old asan_symbolize.py script.
Add compatibility aliases so that old asan_symbolize.py and sanitizer
binaries can work with new llvm-symbolizer.

for the advantage outlined by D83639 ([OptTable] Support grouped short options)
Some behavior changes:
* -i={0,false} is removed. Use --no-inlines instead.
* --demangle={0,false} is removed. Use --no-demangle instead
* -untag-addresses={0,false} is removed. Use --no-untag-addresses instead
Added a higher level API OptTable::parseArgs which handles optional
initial options populated from an environment variable, expands response
files recursively, and parses options.
