The reason for this change was that Mandreel-generated JavaScript leads to a
huge number of deoptimization entries. If we do not increase the limit, we
bail
out and do not use Crankshaft for performance-critical stuff, which is very
bad.
Note that we have some Mandreel code which even needs 16k entries.
I don't know if we should revert this for 3.8 or not, I just wanted to
explain
the motivation behind this change.
