Tweak Sequence.all() and Sequence.any().
...
When possible, they return the actual value from the predicate
instead of always just "true" and "false". This matches && and ||
which evaluate to the RHS or LHS when appropriate.

Added Sequence.count(predicate)
...
Returns the number of elements in the sequence that pass the
`predicate`.
It could also have been implemented as:
count(f) { reduce(0) {|a, b| f.call(b) ? a + 1 : a } }
But I considered the simple version more readable.
Also documented Sequence.count.

Make strings iterable over their code points.
...
I'm not sure why, but this also regresses perf:
binary_trees - wren .......... 3290 0.30s 96.68% relative to baseline
delta_blue - wren .......... 7948 0.13s 99.06% relative to baseline
fib - wren .......... 3165 0.32s 95.90% relative to baseline
for - wren .......... 8242 0.12s 96.00% relative to baseline
method_call - wren .......... 5417 0.18s 78.74% relative to baseline
Need to investigate.
