Vyacheslav Egorov a06b1d96cb Revert "[VM] Reduce Smi size to 32 bit on 64 bit platforms" ... This reverts commit cf78da8a48. Reason for revert: introduces significant performance regression (~30%) on analyzer benchmarks (warm-analysis) without clearly visible hot-spot. Original change's description: > [VM] Reduce Smi size to 32 bit on 64 bit platforms > > This reduces small tagged integers on 64 bit platforms from 63 bits to > 31 bits plus one tag bit. > This is a step on the way to compile-time-optional compressed pointers > on 64 bit platforms. See more about this at go/dartvmlearnings > This causes a slowdown for some uses of integers that don't fit in 31 > signed bits, but because both x64 and ARM64 have unboxed 64 bit > integers now the performance hit should not be too bad. > > This is a reapplication of > https://dart-review.googlesource.com/c/sdk/+/46244 > It was reverted due to a compilation error on 32 bit > ARM with DBC. > > R=​vegorov@google.com > > Change-Id: I943de1768519457f0e5a61ef0b4ef204b6a53281 > Reviewed-on: https://dart-review.googlesource.com/51321 > Reviewed-by: Vyacheslav Egorov <vegorov@google.com> TBR=vegorov@google.com,erikcorry@google.com # Not skipping CQ checks because original CL landed > 1 day ago.
