The new destroy_addr hoisting respects lexical lifetimes. It will replace all other destory hoisting.

[MemAccessUtils] Bailed when visitor bailed.

Previously, in GatherUniqueStorageUses::visiteUse, the results of calls
to visit#### on the visitor were not used.  Here, they are returned from
the function.

replace all other destory hoisting.

[Gardening] Fixed typo.

@nate-chandler
[SSADestroyHoisting] Don't fold trivial loads.
53c728e 
For trivial values, the pattern

  %val = load [trivial] %addr
  destroy_addr %addr

arises.  Don't fold these two into

  %val = load [take] %addr

because that isn't valid SIL for trivial types in OSSA.
@nate-chandler
[SIL] end_apply insts maySynchronize.
b516b04 
Just as a full apply may have side-effects including synchronization, so
may an end_apply, which is lowered to the apply of a continuation.

Code size: -swiftlibs

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).
