This reverts https://dart-review.googlesource.com/c/sdk/+/306674 Patchset 1 is a pure rollback of the rollback. Patchset 2 is https://dart-review.googlesource.com/c/sdk/+/306316 Patchset 4+ is the forward fix for the Fuchsia issues. The Fuchsia bug that we're fixing (or working around), is that VirtualMemory::DuplicateRX doesn't work on Fuchsia. A proper fix will require special casing it, like on MacOS. In the mean time we can avoid using this function by only allowing one page of trampolines on Fuchsia. Unfortunately, when I removed the BSS stuff from the original CL, it was necessary to duplicate even the first page, so I've had to add that stuff back just for Fuchsia.
