66e7209785 Actually load profiling information now! Block layout can use real, live, 
actual profile info, and works!  :)

30c37082ae Fix previous broken commit. A MachineOperand may have opType == 
MO_VirtualRegister but if the register number is one of a physical
register is it considered as a physical register.

ca52c22356 Add an _embarassingly simple_ implementation of basic block layout. This is 
more of a testcase for profiling information than anything that should reasonably
be used, but it's a starting point.  When I have more time I will whip this into
better shape.

d2edafbc32 Remove assert as it is meaningless. MachineOperands can be tagged as 
MO_VirtualRegister but actually be representing a physical register.

4418633216 Implement SimplifyCFG/PhiEliminate.ll 
Having a proper 'select' instruction would allow the elimination of a lot
of the special case cruft in this patch, but we don't have one yet.

286169ff60 Remove and simplify some of the bewildering collection of isFOORegister 
methods which have strangely different semantics in different backends,
and noone knew what any did.

Getting rid of these ALSO allows the dependence of MachineInstr.h on
MRegisterInfo.h to be removed, which makes me much happier, and probably
alkis too.  :)
