runtime/metrics: add tiny allocs metric

Browse source 
Currently tiny allocations are not represented in either MemStats or
runtime/metrics, but they're represented in MemStats (indirectly) via
Mallocs. Add them to runtime/metrics by first merging
memstats.tinyallocs into consistentHeapStats (just for simplicity; it's
monotonic so metrics would still be self-consistent if we just read it
atomically) and then adding /gc/heap/tiny/allocs:objects to the list of
supported metrics.

@ -72,6 +72,13 @@ Below is the full list of supported metrics, ordered lexicographically.
/gc/heap/objects:objects
Number of objects, live or unswept, occupying heap memory.
/gc/heap/tiny/allocs:objects
Count of small allocations that are packed together into blocks.
These allocations are counted separately from other allocations
because each individual allocation is not tracked by the runtime,
only their block. Each block is already accounted for in
allocs-by-size and frees-by-size.
/gc/pauses:seconds
Distribution individual GC-related stop-the-world pause latencies.
