Dhrystone introduced by its removal.

bd3940abc7 Replace the old ADCE implementation with a new one that more simply solves 
the one case that ADCE catches that normal DCE doesn't: non-induction variable
loop computations.

This implementation handles this problem without using postdominators.

b56bc61cf4 Add a flag to indicate that an instruction is as cheap (or cheaper) than a move 
instruction to execute. This can be used for transformations (like two-address
conversion) to remat an instruction instead of generating a "move"
instruction. The idea is to decrease the live ranges and register pressure and
all that jazz.

23dd264da6 Don't attempt to create VZEXT_LOAD out of an extload. This an issue where the 
code generator would do something like this:

f64 = load f32 <anyext>, f32mem
v2f64 = insertelt undef, %0, 0
v2f64 = insertelt %1, 0.0, 1

into 

v2f64 = vzext_load f32mem

which on x86 is movsd, when you really wanted a cvtss2sd/movsd pair.
