Tim Northover 11a2354670 GlobalISel: use G_TYPE to annotate physregs with a type. 
More preparation for dropping source types from MachineInstrs: regsters coming
out of already-selected code (i.e. non-generic instructions) don't have a type,
but that information is needed so we must add it manually.

This is done via a new G_TYPE instruction.

Dean Michael Berris 047669f18c [XRay] Support multiple return instructions in a single basic block 
Add a .mir test to catch this case, and fix the xray-instrumentation
pass to handle it appropriately.
