Time to move std.experimental.checkedint to std.checkedint ?

Some micro-architectures employ an L0/uOp cache, which can 
significantly alter the I$ performance calculus within loops.  To 
confidently identify an I$ performance bottleneck I think you'd 
need to use perf analysis tools. IIRC Max recommended this at 
Beerconf.

Side note: the checkedint code sure looks nice.  It's a very 
readable example of the leverage D affords.
