Summary: In the mode when ASan shadow base is computed as the address of an external global (__asan_shadow, currently on android/arm32 only), regalloc prefers to rematerialize this value to save register spills. Even in -Os. On arm32 it is rather expensive (2 loads + 1 constant pool entry). This changes adds an inline asm in the function prologue to suppress this behavior. It reduces AsanTest binary size by 7%.
