Xin Tong	8cb15cfc13	Improve what can be promoted in LICM. ... Summary: In case of non-alloca pointers, we check for whether it is a pointer from malloc-like calls and it is not captured. In such case, we can promote the pointer, as the caller will have no way to access this pointer even if there is unwinding in middle of the loop.
