Change:

@clz(comptime T: type, integer: T)
@ctz(comptime T: type, integer: T)
@popCount(comptime T: type, integer: T)

to

@clz(value: anytype)
@ctz(value: anytype)
@popCount(value: anytype)

Because llvm.ctlz, llvm.cttz and llvm.ctpop supports vectors with integer element type.

It's breaking changes.
