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.
