Functions
ffi::Array< PrimExpr >	tvm::sym::DetectLinearEquation (const PrimExpr &e, const ffi::Array< PrimVar > &vars)
	Detect if e can be rewritten as e = sum_{i=0}^{n-1} var[i] * coeff[i] + coeff[n] Where coeff[i] and base are invariant of var[j] for all i and j.
ffi::Array< ffi::Optional< PrimExpr > >	tvm::sym::DetectClipBound (const PrimExpr &e, const ffi::Array< PrimVar > &vars)
	Detect if expression corresponds to clip bound of the vars.
