GDC and LDC can not detect it, I don't think DMD can. Proof - 
https://godbolt.org/g/bsAFU8 .
Your link refers to GDC with an old DRuntime, which have bsr 
intrinsics instead of current software code.

In addition, i need to be sure that an intrinsics function is 
always inlined (without -inline flag too).
