Add new pass LazyMachineBlockFrequencyInfo
And use it in MachineOptimizationRemarkEmitter. A test will follow on top of
Justin's changes to enable MachineORE in AsmPrinter.
The approach is similar to the IR-level pass. It's a bit simpler because BPI
is immutable at the Machine level so we don't need to make that lazy.
Because of this, a new function mapping is introduced (BPIPassTrait::getBPI).
This function extracts BPI from the pass. In case of the lazy pass, this is
when the calculation of the BFI occurs. For Machine-level, this is the
identity function.
