TARGET_SCHED_PROLOG defined twice

[Marcin Dalecki]

Looking at rs6000.opt I have found that the above command line switch  
variable is defined TWICE:

msched-prolog
Target Report Var(TARGET_SCHED_PROLOG) Init(1)
Schedule the start and end of the procedure
msched-epilog
Target Undocumented Var(TARGET_SCHED_PROLOG) VarExists

This appears of course to be wrong.
