Compile-time memory footprint of std.algorithm

[Iain Buclaw via Digitalmars-d]

Testing a 2.065 pre-release snapshot against GDC. I see that 
std.algorithm now surpasses 2.1GBs of memory consumption when 
compiling unittests.  This is bringing my laptop down to its 
knees for a painful 2/3 minutes.

This is time that could be better spent if the unittests where 
simply broken down/split up.
