Try both ways to fold an add together. This allows us to generate this code
imul %EAX, %EAX, 400
add %ECX, %EAX
add %ESI, DWORD PTR [%ECX + 4*%EDX]
inc %EDX
cmp %EDX, 100
instead of this:
imul %EAX, %EAX, 400
add %ECX, %EAX
mov %EAX, %EDX
shl %EAX, 2
add %ECX, %EAX
add %ESI, DWORD PTR [%ECX]
inc %EDX
cmp %EDX, 100
