!!!Please add intrinsics module for DMD DRuntime!!!

[Ilya Yaroshenko via Digitalmars-d]

Hey all,

Please add a module (core.intrinsics ?) which will contain all 
DMD intrinsics similar to ldc.intrinsics. After each DMD release 
it is not clear what is intrinsics and what is not. I need BSF 
intrinsics for Better C library Mir Random [1], which should work 
without linking with DRuntime and Phobos. I can use 
ldc.intrinsics for LDC, but have no idea about DMD. I want BSR 
and BSF instructions to be generated instead of current 
_software_ implementation in core.bitop.

==================
Philosophical Questions:

1. Why hight level stuff like BitRange is in core.bitop, but not 
in std.bitmanip? If it should be in core, why it is public?

2. Why bsf and bsr do NOT use hardware instructions anymore?
==================

Please ping me for Phobos and DRuntime PRs if they are related to 
math and numeric issues.

Best regards,
Ilya
