If an inline function is observed but unused in a translation unit, dummy
coverage mapping data with zero hash is stored for this function.
If such a coverage mapping section came earlier than real one, the latter
was ignored. As a result, llvm-cov was unable to show coverage information
for those functions.

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.

Coverage mapping data is organized in a sequence of blocks, each of which is expected
to be aligned by 8 bytes. This feature is used when reading those blocks, see
VersionedCovMapFuncRecordReader::readFunctionRecords(). If a misaligned covearge
mapping data has more than one block, it causes llvm-cov to fail.

CovMapFuncReader::get should propagate up errors from InstrProfSymtab.
This is part of a series of patches to transition ProfileData over to
the stricter Error/Expected interface.
