vm: simplify slot and make it private
Hiding refcounter inside a slot is actually a good idea, but it makes the
structure somewhat bigger, especially given that the refcounter is the same
and belongs more to VM or Context. New structure is a bit more efficient:
name old time/op new time/op delta
ScriptFibonacci-8 672µs ± 2% 644µs ± 0% -4.15% (p=0.008 n=5+5)
ScriptNestedRefCount-8 1.08ms ± 1% 1.05ms ± 2% -2.56% (p=0.008 n=5+5)
ScriptPushPop/4-8 1.52µs ± 1% 1.47µs ± 1% -3.14% (p=0.008 n=5+5)
ScriptPushPop/16-8 3.66µs ± 1% 3.54µs ± 1% -3.24% (p=0.008 n=5+5)
ScriptPushPop/128-8 24.7µs ± 1% 23.2µs ± 1% -6.14% (p=0.008 n=5+5)
ScriptPushPop/1024-8 183µs ± 1% 173µs ± 1% -5.01% (p=0.008 n=5+5)
name old alloc/op new alloc/op delta
ScriptFibonacci-8 114kB ± 0% 114kB ± 0% ~ (p=0.079 n=4+5)
ScriptNestedRefCount-8 241kB ± 0% 241kB ± 0% ~ (p=0.333 n=5+4)
ScriptPushPop/4-8 160B ± 0% 160B ± 0% ~ (all equal)
ScriptPushPop/16-8 640B ± 0% 640B ± 0% ~ (all equal)
ScriptPushPop/128-8 8.70kB ± 0% 8.70kB ± 0% ~ (all equal)
ScriptPushPop/1024-8 73.2kB ± 0% 73.2kB ± 0% ~ (all equal)
name old allocs/op new allocs/op delta
ScriptFibonacci-8 3.17k ± 0% 3.17k ± 0% -0.03% (p=0.008 n=5+5)
ScriptNestedRefCount-8 10.7k ± 0% 10.7k ± 0% ~ (all equal)
ScriptPushPop/4-8 8.00 ± 0% 8.00 ± 0% ~ (all equal)
ScriptPushPop/16-8 32.0 ± 0% 32.0 ± 0% ~ (all equal)
ScriptPushPop/128-8 259 ± 0% 259 ± 0% ~ (all equal)
ScriptPushPop/1024-8 2.05k ± 0% 2.05k ± 0% ~ (all equal)
It'd be especially nice to internalize static slot, but as we can't compare
slices it's not possible.
