Do you have some examples? I can see that
a = 1.0
b = sin(a)
could now be optimized, but I don't see that being a common pattern.
(Also, if a is typed, gcc is likely to already be able to do this.)

Possibly a first (and more fruitful) step to investigate would be more
local type inference (e.g a variable might be a double within a block,
and only need to be used as/store an object elsewhere.
