[MachineSink] Allow sinking of constant or ignorable physreg uses
For AMDGPU, any use of the physical register EXEC prevents sinking even if it is not a real physical register read. Add check to see if a physical
register use can be ignored for sinking.
Also perform same constant and ignorable physical register check when considering sinking in loops.
