Delete the colon from RUN: for examples, since it's not there for tests.
Add spaces to line up RUN and PASS: lines.
Before:
=== RUN TestCount
--- PASS: TestCount (0.00s)
=== RUN: ExampleFields
--- PASS: ExampleFields (0.00s)
After:
=== RUN TestCount
--- PASS: TestCount (0.00s)
=== RUN ExampleFields
--- PASS: ExampleFields (0.00s)

There are 3 issues:
1. Skip argument of callers is off by 3,
so that all allocations are deep inside of memory profiler.
2. Memory profiling statistics are not updated after runtime.GC.
3. Testing package does not update memory profiling statistics
before capturing the profile.
Also add an end-to-end test.
Fixes#8867.
