Matthias Braun 90799ce8b2 MachineFunction: Introduce NoPHIs property ...

I want to compute the SSA property of .mir files automatically in
upcoming patches. The problem with this is that some inputs will be
reported as static single assignment with some passes claiming not to
support SSA form.  In reality though those passes do not support PHI
instructions => Track the presence of PHI instructions separate from the
SSA property.
