And are there any docs?

there are some pragmas for bitop stuff.
https://github.com/ldc-developers/ldc/blob/master/gen/pragma.cpp#L59

there are target agnostic intrinsics

https://github.com/ldc-developers/druntime/blob/ldc/src/ldc/intrinsics.di

Additionally any function from

https://github.com/llvm-mirror/llvm/blob/master/include/llvm/IR/Intrinsics.td#L252

or from any of the files included at the bottom of that file
https://github.com/llvm-mirror/llvm/blob/master/include/llvm/IR/Intrinsics.td#L968

may be used in a
```
pragma(LDC_intrinsic, "llvm.foo")
void llvm_foo();
```

declaration, provided you are targeting the appropriate hardware.
