Simplify the coalescer (finally!) by making LiveIntervals::processImplicitDefs a little more aggressive and teaching liveintervals to make use of isUndef marker on MachineOperands.

is the right fix but at least it keeps opt from crashing.

Make DOUT an lvalue in release mode so that developers may use DOUT in
their code in release mode.  This helps to debug release-mode problems.

Add logic to align instruction operands to columns for pretty-printing.
No target uses this currently.  This patch only adds the mechanism so
that local installations can choose to enable this.

isSafeToSpeculativelyExecute. The new method is a bit closer to what 
the callers actually care about in that it rejects more things callers 
don't want.  It also adds more precise handling for integer 
division, and unifies code for analyzing the legality of a speculative 
load.
