Why Memory Sanitizer support x86_64 only

> MemorySanitizer run-time library shares much common code with AddressSanitizer and ThreadSanitizer libraries. At startup it makes the lower protected area inaccessible, and maps Shadow and, optionally, Origin areas. MemorySanitizer is currently limited to Linux / x86 64, and these memory ranges (as specified in Figure 1) are always available at startup, provided that the application is linked as PIE (position-independent executable), and address space layout randomization (ASLR) is enabled.[1]
