Zhiwei Chen dbc641deb9 [sanitizer] Reduce redzone size for small size global objects ...

Currently 1 byte global object has a ridiculous 63 bytes redzone.
This patch reduces the redzone size to be less than 32 if the size of global object is less than or equal to half of 32 (the minimal size of redzone).
A 12 bytes object has a 20 bytes redzone, a 20 bytes object has a 44 bytes redzone.
