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.

Added ability to estimate the entry count of the extracted function and
the branch probabilities of the exit branches.

-view-machine-block-freq-propagation-dags currently
support integer and fraction as the suboptions. This
patch adds the 'count' suboption to display actual
profile count if available.

Moves redundant template parameters into an implementation detail of
BlockFrequencyInfoImpl.
No functionality change.

This is a shared implementation class for BlockFrequencyInfo and
MachineBlockFrequencyInfo, not for BlockFrequency, a related (but
distinct) class.
No functionality change.

Implement Pass::releaseMemory() in BlockFrequencyInfo and
MachineBlockFrequencyInfo. Just delete the private implementation when
not in use. Switch to a std::unique_ptr to make the logic more clear.
<rdar://problem/14292693>
llvm-svn: 204741
This is useful for debugging issues in the BlockFrequency implementation
since one can easily visualize where probability mass and other errors
occur in the propagation.
This is the MI version of r194654.
