[PATCH] D67216: [cfi] Add flag to always generate call frame information

[Eric Christopher via llvm-commits]

That said, prior art in gcc in this area:

-fasynchronous-unwind-tables

Generate unwind table in DWARF format, if supported by target machine.
The table is exact at each instruction boundary, so it can be used for
stack unwinding from asynchronous events (such as debugger or garbage
collector).
