Option parsing tables: pick up AliasArgs from the OPTION macro.

This depends on LLVM r187537.

The SUPPORT_ALIASARGS macro will be removed once all option parsing
clients have been updated.

clang-format: Add more options to namespace indentation.

With this patch, clang-format can be configured to:
* not indent in namespace at all (former behavior).
* indent in namespace as in other blocks.
* indent only in inner namespaces (as required by WebKit style).

Also fix alignment of access specifiers in WebKit style.

Patch started by Marek Kurdej. Thank you!

Make -m[no-]pascal-strings an alias of -f[no]pascal-strings in the .td file

This way we don't have to translate it manually in Clang::ConstructJob.
