With PR33517, it became apparent that symbol table creation can fail
when presented with malformed inputs. This patch makes that sort of
error detectable, so llvm-cov etc. can fail more gracefully.
Specifically, we now check that function records loaded from corrupted coverage
mapping data are rejected, e.g when the recorded function name is garbage.
Testing: check-{llvm,clang,profile}, some unit test updates.

I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.
I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.
This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.
Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

Now that we have dropped MSVC 2013, all supported compilers support
noexcept and we can drop this portability macro.

Add support for loading multiple coverage readers into a single
CoverageMapping instance. This should make it easier to prepare a
unified coverage report for multiple binaries.

Pass a `MemoryBuffer &` to BinaryCoverageReader::create() instead of a
`std::unique_ptr<MemoryBuffer> &`. This makes it easier to reason about
the ownership of the buffer at a glance.

Transition InstrProf and Coverage over to the stricter Error/Expected
interface.
Changes since the initial commit:
- Fix error message printing in llvm-profdata.
- Check errors in loadTestingFormat() + annotateAllFunctions().
- Defer error handling in InstrProfIterator to InstrProfReader.
- Remove the base ProfError class to work around an MSVC ICE.
