Andrew Trick 55ba5dff3c RegPressure: API for speculatively checking instruction pressure. 
Added getMaxExcessUpward/DownwardPressure. They somewhat abuse the
tracker by speculatively handling an instruction out of order. But it
is convenient for now. In the future, we will cache each instruction's
pressure contribution to make this efficient.
