Expand description

Equivalent to the appropriate llvm.memset.p0i8.* intrinsic, with a size of count * size_of::<T>() and an alignment of min_align_of::<T>().

The volatile parameter is set to true, so it will not be optimized out unless size is equal to zero.

This intrinsic does not have a stable counterpart.
