  Revert [MC][ELF] Emit separate unique sections for different flags

Commit Message from @MaskRay:

Rust has a fragile embed-bitcode implementation
(https://github.com/rust-lang/rust/blob/bddb59cf07efcf6e606f16b87f85e3ecd2c1ca69/compiler/rustc_codegen_llvm/src/back/write.rs#L970-L1017)
which relied on the previous LLVM MC behavior.  Rust's LLVM fork
has carried a revert. This commit made the similar revert to help
distributions since they would otherwise probably carry a similar patch
(as they ship rust linked against system LLVM).

Fixes https://bugs.llvm.org/show_bug.cgi?id=51207.
