  Log Message:
  -----------
  [pmc] change StringBuilder overallocation

by 1.5, not 2. And for >8192 onto the next block size.
The optimal overallocation is the golden ration 1.618, but we prefer int ops.
A difference is not measurable.

  Log Message:
  -----------
  [pmc] disable 2x StringBuilder.substr clone, GH #1123

STRING_substr already creates a copy for us, no need to copy it twice.
no regression.

Note that t/stress/gc.t started failing earlier, even in 7.0.0.

  Log Message:
  -----------
  [pmc] rpa gc optimizations

Re-enable the status from 6.11.0, not too many write barriers in
ResizablePMCArray methods. Not in shift as we only move the offset
and only when needed in resize.
But it does not give us back the lost 13% in parrot-bench, from 6.11
to 7.0.
