  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.

  [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.
