Enable bunch of sanitizers on NetBSD/X86 and X86_64

[krytarowski]

Summary

Enable more sanitizers:

• i386 and amd64:
• SanitizerKind::Vptr;
• SanitizerKind::Leak;
• SanitizerKind::SafeStack;
• SanitizerKind::Function;
• amd64 only:
• SanitizerKind::Thread;

These sanitizers are in the process of upstreaming to LLVM projects.
