Igor Kudrin 5a4a55829a [Coverage] Ensure that coverage mapping data has an expected alignment in 'covmapping' files. ...

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.
