@swift-ci test

@swift-ci smoke benchmark

[gottesmm]

Not much to change in this pass since it is mainly dealing with projections/destroy_addr/copy_addr

LGTM

nit : Add : after // CHECK-LABEL: sil [ossa] @test_enum_with_initialize
Same in all functions below

[gottesmm]

Thanks! You are right! I should have fixed! I'll fix after the tests pass and then do a smoke test

How to read the data

The tables contain differences in performance which are larger than 8% and differences in code size which are larger than 1%.

If you see any unexpected regressions, you should consider fixing the
regressions before you merge the PR.

Noise: Sometimes the performance results (not code size!) contain false
alarms. Unexpected regressions which are marked with '(?)' are probably noise.
If you see regressions which you cannot explain you can try to run the
benchmarks again. If regressions still show up, please consult with the
performance team (@eeckstein).
