Fix typos in comments of ExecutionEngine/

[sgraenitz]

Wow, that's a lot of typo fixes! Thanks!

Let's drop all the an <--> a changes, I think these are fine.

Everything else LGTM.

Though it's a very minor thing, I wanted to remove all of the "a ELF " usage in the whole project including lldb https://reviews.llvm.org/D157214. I can revert them with no problem.

Reverted a -> an changes for acronyms in comments

LGTM, thanks! Should I land it on your behalf?

I think we could keep this as well. Was it by accident?

Yes please. You can use:

It is the only non-acronym pattern so I left it out.

Oh cool -- thanks very much for this @Eymay!
