e3e8ea5d65 [flags] Rename --opt to --turbofan 
To be consistent with the all the other tiers and avoid confusion, we
rename --opt to ---turbofan, and --always-opt to --always-turbofan.

f44027169d Quick fix for array reduction tests 
These tests are likely missing %PrepareFunctionForOptimization
annotation of lambdas. Thus lambdas are no longer inlined and
%DeoptimizeNow does nothing, while the entire point of these tests is
to test deoptimization paths.

Disabling lazy feedback allocation is a quick fix to restore coverage
until we can land a more complete fix (for details see the linked
bug).
