For an if block
if (cond)
{
<then_block>
}
else
{
<else_block>
}
We flatten it by first replacing any store instruction `v[[k]] = x`
in the then_block with the following:
1: load(v[[k]])
2: cond ? x : @1
3: v[[k]] = @2
Similarly, we replace any store instruction `v[[k]] = x` in the
else_block with the following:
1: load(v[[k]])
2: cond ? @1 : x
3: v[[k]] = @2
Then we can concatenate <then_block> and <else_block> together and
get rid of the if block.
