But I think that LLVM should have a small finite number of intrinsics for patchpoint, and the frontend (JIT client) should be able to pass it a symbolic target with any signature. In other words, we should always treat the target arguments as varargs from the intrinsic's point of view. That doesn't change the actual calling convention used.
Andy, I think you may have misread the change.  The suggestion is not 
changing either the calling convention or the encoding of the arguments 
passed to the target function.  It's changing the type of the target 
function itself.  Instead of being an i8*, it could be a void(int)* for 
example.  The intrinsic would become parametric with the type of the 
target.

Currently, you have to explicitly bitcast your function type to an i8* 
before passing it to the patchpoint.  This change would remove that 
requirement.
