Second sub-CL of https://dart-review.googlesource.com/c/sdk/+/100644 The first was here https://dart-review.googlesource.com/c/sdk/+/103487 Now that offsets_extractor is checked in, and we have a big header full of hard coded constants, the next step is to make sure everything is using those constants. This is essentially everything in the original CL, except the new simarm_x64 architecture. Bug: https://github.com/dart-lang/sdk/issues/36839 Change-Id: I236e4f30aa1df6d92209891c983b792d1835b608 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/104286 Commit-Queue: Liam Appelbe <liama@google.com> Reviewed-by: Ryan Macnak <rmacnak@google.com>
