Strength reduction is replacement of operations such as "i = j * 8" by
"i = j << 3", or "i = j % 8" by "i = j & 0x3" (if j is unsigned).

As for source-to-source translation: not for me. A lot of the optimizations
(dead-code analysis, colored register allocation, etc) isn't at the level
of the source code.
	It is this class of optimization which kills statements such as
"n = n;". You could recognize ``useless'' statements like this & warn the
person about it, but I think it would be better to simply dis-able the
optimizations at that point and/or code that little-needed routine
in assembly code.
	Vector & concurrentization optimizations can usually be done in
a source-source fashion, but this stuff would just fill your source files
up with meaningless garbage which is impossible to edit/maintain. The
only ``source'' which it would be reasonable to convert it to is assembler.
