I guess !global_regs[regno] vs !fixed_regs[regno] matters for compilation units
that are compiled with -ffixed-$N but where there is no global register
variable declaration for $N in scope.  Can you construct a C test case which
shows that gcc clobbers a register $N even though the file is compiled with
-ffixed-$N ?
