I just found that at least on Skylake CPUs cpu_ticks() never returns odd
values, only even, and possibly has even bigger step (176/2?), that makes
its lower bits very bad entropy source, leaving half of taskqueues unused.
Switch to sbinuptime(), closer to upstreams, mitigates the problem by the
rate conversion working as kind of hash function.  In case that is somehow
not enough (timer rate is too low or too divisible) mix in curcpu.

Fix inline assembler constraint validation

  The current constraint logic is both too lax and too strict. It fails
  for input outside the [INT_MIN..INT_MAX] range, but it also
  implicitly accepts 0 as value when it should not. Adjust logic to
  handle both correctly.

Pull in r355491 from upstream clang trunk (by Hans Wennborg):

  Inline asm constraints: allow ICE-like pointers for the "n"
  constraint (PR40890)

  Apparently GCC allows this, and there's code relying on it (see bug).

  The idea is to allow expression that would have been allowed if they
  were cast to int. So I based the code on how such a cast would be
  done (the CK_PointerToIntegral case in
  IntExprEvaluator::VisitCastExpr()).

These should fix assertions and errors when using the inline assembly
"n" constraint in certain ways.

In case of devel/valgrind, a pointer was used as the input for the
constraint, which lead to "Assertion failed: (isInt() && "Invalid
accessor"), function getInt".

In case of math/secp256k1, a very large integer value was used as input
for the constraint, which lead to "error: value '4624529908474429119'
out of range for constraint 'n'".

This matches GNU seq, for example.

For users that are looking for similar functionality, 'jot -b foo N' will
print 'foo' N times.  See jot(1).

The ports version of cal is an abandonware so in order to minimize the
potential bit rot of our documentation let's not mention it at all.
Interested users are going to find suitable alternatives anyway on their
own.
