Reopening this one since the cases in this bug report (unknown stride,
conditional candidate) are not yet handled by the new strength reduction pass.
I will re-close once those additional features are in place.

The unknown stride features made it into 4.8.0, but conditional candidates are
still pending, and too complex for 4.8.1, I think. Changing target to 4.9 for
the remaining work. I do plan to get that wrapped up fairly soon.

Conditional candidate processing was completed a couple of months ago. While
there are improvements I plan to look at someday, the basic work is done, so
closing the issue.

Seems to be a missing functionality
int a[100];
int g;
void foo(int i)
{
a[i] = i*g;
i++;
a[i] = i*g;
i++;
a[i] = i*g;
}
Both array address computation and RHS mpy operations can be strength reduced.
