+/// CalleeSavedRegs - A list of callee saved registers for a given calling

+/// allocation stack slots for saved registers.

+/// For each CalleeSavedRegs def, TableGen will emit a FOO_SaveList array for
+/// returning from getCalleeSavedRegs(), and a FOO_RegMask bit mask suitable for
+/// returning from getCallPreservedMask().
