* checks.adb (Minimize_Eliminate_Overflow_Checks): Dont reanalyze
if/case expression if nothing has changed (just reexpand). Stops
case expression from generating incorrect temporary.
* exp_ch4.adb (Expand_Compare_Minimize_Eliminate_Overflow):
Fix cut and paste typo for range analysis in NE (not equal) case.
* sem_eval.adb (Compile_Time_Compare): Small optimization to
catch some more cases.
* types.ads (Suppressed_Or_Checked): New subtype of
Overflow_Check_Type.
