Yep, it is just heuristic here.  We may get more cureful at -Os (i.e. not so
optimistic about the optimization oppurtunities), but last time I played with
this it actually resulted in code size increase at Mozilla and -Os.

LLVM is doing kind of oposite heuristic tracking when function gets address of
local variable as a parameter and anticipate SRA then. I suppose I can give
this a try even though it will miss all the optimization of dynamically
allocated objects...
