[phobos] Converting function pointers to delegates

[David Simcha]

A pretty significant wart of D is that function pointers and delegates 
are completely incompatible.  I've come up with a good hack to convert 
function pointers to delegates without any heap allocations or 
additional storage besides the delegate itself being used.  In 
particular, there are no heap allocations, closures, etc. involved.  
However, calling a delegate created from a function pointer does still 
incur two indirect function calls instead of one.  I've attached the 
code.  Tell me what you think.
