Depends, it allows you to add support for locking-mechanisms/SIMD 
instructions/etc before getting language support. You want that 
inlined and the compiler to do register assignment. I believe 
LLVM just pass it on to the assembler almost verbatim. If done 
right you wouldn't need to update the compiler in order to add 
support for new instructions/trap mechanisms, updating an 
external assembler should be sufficient, so it is a future-proof 
technology. I think inline asm wrapped up as inline functions is 
pretty neat, in the rare case where you need it (some rare CPUs 
have built in true random() functionality for instance).
