Building a wasm library, need to override .object._d_newitemT!T

[Etienne Cimon]

Hello,

I've been developing a library[1] based on spasm for which I've 
implemented the druntime and currently it compiles web apps 
properly with TypeInfo, no GC, and it even uses diet templates.

I'm having a problem implementing the `new` keyword, so that I 
can start importing more libraries with minimal change. However, 
LDC calls .object._d_newitemT!T from the original druntime - 
which I need for compile-time function execution, but my 
implementation in `module object` doesn't override it in the 
compiler and the original implementation tries import 
core.stdc.time which errors out in wasm (with good reasons). Is 
there a compiler flag than I can use to override module templates?

Thanks in advance.
