This commit fixes the following problems:

  • The x86_64 trampolines are not preserving frame pointers
  • The hardcoded offsets to the code segment from the FDE only worked properly for x64_64
  • The CIE data was not following conventions of aarch64
  • The eh_frame for aarch64 was not fully correct
    (cherry picked from commit 236f733)
