Where is there documentation on how to write inline asm?

The MS docs are complete IIRC. The pointer to the pre-allocated 
result of your 16-bytes struct is passed in RCX.
If unsure, just reverse-engineer what you need: type it down in 
normal D and analyze the generated assembly. You can even do so 
online via run.dlang.io (https://run.dlang.io/is/rhsDBF); just 
select LDC and add `-mtriple=x86_64-pc-windows-msvc` to generate 
Win64 assembly.
Note that run.dlang.io displays AT&T-style asm, not the Intel 
one. You can use LDC offline via `-output-s 
-x86-asm-syntax=intel` to generate a .s file with Intel syntax.
