WIP patch

this patch cuts some redundant work on estimating size of functions that will
be too large to be inlined anyway. Currently inliner spends a lot of time
compuing properties of these functions (since small and inlinable functions are
also fast to estimate)

The patch doesn't really save much time building libreoffice/firefox. I will
experiment with it a bit more.
