This patch effectively reverts a small part of D83979.
When we stop parsing `LangOpts` unconditionally in `parseSimpleArgs` (above the diff) and move them back to `ParseLangArgs` (called in `else` branch) in D94682, `LangOpts.PIE` would never get parsed in this `if` branch. This patch ensures this doesn't happen.
Right now, this causes `LangOpts.PIE` to be parsed twice, but that will be immediately corrected in D94682.
