This hack was intended to handle the case where `-Clto=thin` causes the compiler to emit multiple output files (when producing LLVM-IR or assembly). The hack only affects 4 tests, of which 3 are just meta-tests for the hack itself. The one remaining test that motivated the hack currently doesn't even need it!

Mostly reverts #118036, which was trying to fix a test failure observed in #113923. I do think it's reasonable for compiletest to have some way of handling the multiple-output-file scenario for these test suites, but:

compiletest: Simplify the choice of `--emit` mode for assembly tests Tiny little cleanup that I noticed while working on rust-lang#131524. No functional change. Historically, the original code structure (rust-lang#58791) predates the `Emit` enum (rust-lang#103298), so it was manually adding `--emit` flags to the compiler invocation. But now the match can just evaluate to the appropriate `Emit` value directly.
