the compiler knows the pragma #callee_saves [function1][,function2].

If the compiler option --callee_saves is used then it makes sense to have a
#pragma caller_saves [function1][,function2]
as well.

(would be used for functions which use many registers which are
called from a function with (locally) low register pressure)
