Dropping support for `-embed-bitcode` was brought up in the original RFC for FatLTO. The plan I recall was to deprecate the option, make it CC1 , and see if MLGO (the only remaining user we're aware of) could use a different solution and if they could, then drop it altogether.

The important bits start roughly here https://discourse.llvm.org/t/rfc-ffat-lto-objects-support/63977/15, but there are some other points raised earlier in the thread too. In light of that plan, I'm not too sure how important it is to provide support for `.llvmbc`.

@mtrofin, since I think you would be impacted by significant changes in this area, do you have thoughts here?
