The ShowCrashReports() feature for aarch64 should work even better than the x86 crash reports. Thanks to the benefit of hindsight these reports should be rock solid reliable and beautiful to read. This change also improves the syscall polyfills for aarch64. Some of the sys_foo() functions have been removed, usually because they're legacy or downright footguns not worth building.
