function arguments and arguments for variadic functions are of a particular
type which is determined by some other argument to the same function call.
Usecases include:
* MPI library implementations, where these attributes enable checking that
buffer type matches the passed MPI_Datatype;
* for HDF5 library there is a similar usecase as MPI;
* checking types of variadic functions' arguments for functions like
fcntl() and ioctl().

Select instructions pick one of two virtual registers based on a

selects can sometimes be eliminated by predicating the instruction
defining one of the operands.

target to optimize them.
