Justin Lebar c75d566f56 When printing MIR, output to errs() rather than outs(). 
Summary:
Without this, this command

  $ llvm-run llc -stop-after machine-cp -o - <( echo '' )

outputs an error, because we close stdout twice -- once when closing the
file opened for "-o", and again when closing outs().

Also clarify in the outs() definition that you can't ever call it if you
want to open your own raw_fd_ostream on stdout.

Junmo Park 7ceec0b82f [BranchFolding] Set correct mem refs (2nd try) 
This is a recommit of r257253 which was reverted in r257270.
Previous testcase can make failure on some targets due to using opt with O3 option.

Original Summary:
Merge MBBICommon and MBBI's MMOs.
