arm64e platforms. On arm64e-capable Apple platforms, the system libraries are always arm64e, but applications often are arm64. When a target is created from file, LLDB recognizes it as an arm64 target, but debugserver will still (technically correct) report the process as being arm64e. For consistency, set the target to arm64 here. rdar://92248684 Differential Revision: https://reviews.llvm.org/D133069
