Daniil Fukalov 65469277ca [SCEV] limit recursion depth and operands number in getAddExpr

for a quite big function with source like

%add = add nsw i32 %mul, %conv
%mul1 = mul nsw i32 %add, %conv
%add2 = add nsw i32 %mul1, %add
%mul3 = mul nsw i32 %add2, %add
; repeat couple of thousands times
that can be produced by loop unroll, getAddExpr() tries to recursively construct SCEV and runs almost infinite time.

Added recursion depth restriction (with new parameter to set it)
