Dan reported two smatch warnings [1],
.. warn: should '1 << lclusterbits' be a 64 bit type?
.. warn: should 'm->compressedlcs << lclusterbits' be a 64 bit type?
In practice, m_plen cannot be more than 1MiB due to on-disk constraint
for the compression mode, so we're always safe here.
In order to make static analyzers happy and don't report again,
let's silence them instead.
