coverage: Rearrange the code for embedding per-function coverage metadata This is a series of refactorings to the code that prepares and embeds per-function coverage metadata records (“covfun records”) in the `__llvm_covfun` linker section of the final binary. The `llvm-cov` tool reads this metadata from the binary when preparing a coverage report. Beyond general cleanup, a big motivation behind these changes is to pave the way for re-landing an updated version of #133418. --- There should be no change in compiler output, as demonstrated by the absence of (meaningful) changes to coverage tests. The first patch is just moving code around, so I suggest looking at the other patches to see the actual changes. --- try-job: x86_64-gnu try-job: x86_64-msvc try-job: aarch64-apple
