[OT] LLVM tricks

[Sergey]

Nice article with some interesting gotchas about LLVM IR 
optimizations. The article mostly about Zig, but as it stated 
"That’s a theme—any trick you do with LLVM IR would work for any 
LLVM-based language."

Wonder if those kind of analysis is possible to re-implement for 
LDC :)
Hope someone else will find this info useful too.
