Fangrui Song c63038b191 [llvm-size] Switch command line parsing from llvm::cl to OptTable
Part of https://lists.llvm.org/pipermail/llvm-dev/2021-July/151622.html
"Binary utilities: switch command line parsing from llvm::cl to OptTable"

* `--totals=false` and `--totals=0` cannot be used. Omit the option.
* `--help-list` is removed. This is a `cl::` specific option.

OptTable avoids global option collision if we decide to support multiplexing for binary utilities.

Note: because the tool is simple, and its long options are uncommon, I just drop
the one-dash forms except `-arch <value>` (Darwin style).
