Alexander Markov 7f40a291ae [vm] Fix debug/arm64c build 
On arm64 Address can assume certain load/store size depending on the
value (alignment) of the offset. This may cause assertion failure

  "runtime/vm/compiler/assembler/assembler_arm64.h: 2750: error: expected: a.log2sz_ == -1 || a.log2sz_ == size".

This change fixes build on arm64c in debug mode by using an unaligned
offset. This is a follow-up to https://dart-review.googlesource.com/c/sdk/+/259920.

TEST=Build on the vm-ffi-android-debug-arm64c bot.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
