Eric was hoping for some API improvements here as we add more tuning options, but I don't think these need to be sequenced.

@asbirlea, are you sure this was enabled by default before? (cl::init(true))
I've traced regressions in r600 and amdgcn to this patch.
Both can be fixed by changing the default to false.
While those regressions look like backend bugs, the commit message says NFC.

@jvesely: Yes, you are right. D61955 should resolve this.
