The use of the packed attribute can cause a performance penalty for
all accesses to the struct members, as the compiler will assume that the
structure has the potential to have an unaligned base.
These structures are all correctly aligned and contain no holes, thus
the attribute is redundant and negatively impacts performance, so we
remove the attributes entirely.
