ARM Cortex-M Microcontroller startup files

Martin,

This is a bit of a tangent, but I would like to know what your 
thoughts are on this:

The problem is that when we use an unimplemented feature of D, 
the best we can hope for is to generate a linker error.  I 
proposed this idea as a way to make the conversation between the 
user and their druntime implementation more polished.  The 
runtime implementation, through its .di files informs the 
compiler and user what is and isn't supported so the user can get 
friendly compile-time errors and the compiler can make better 
assumptions about codegen.
