S_invlist_trim - don't SvPV_renew where no change is likely
Currently, `S_invlist_trim` always calls `SvPV_renew(invlist, <size>)`,
which is a macro wrapping a call to `safesysrealloc()`.
However, `SvLEN(invlist)` is often already exactly the desired size, or
it is larger by less than the size of a pointer. With this commit, the
new `expected_size` macro is used to reduce the number of cases in which
S_invlist_trim will try to shrink a buffer but no shrinkage is likely to
occur. (For example, if the desired size is less than the minimum actual
allocation size.)
