GDC adds intrinsic support for core.checkedint

[Iain Buclaw via Digitalmars-d]

Hi,

GDC now recognizes all functions in core.checkedint as 
intrinsics.  May you all enjoy using inlined, hardware leveraged, 
overflow-checking integer operations.

I say 'you all', but what I really mean is 'bearophile'. :-)
