Log Message:
-----------
[gc] fix the GC regression GH #1159 in resizablepmcarray
Always do PARROT_GC_WRITE_BARRIER with rpa unshift, even with the fast case.
The same with resize skip, where only the right side is adjusted.
Just skip the WB when the old size == new size.
This should fix the gc errors on small machines with big programs.
parrot-bench is now 1.2% slower.
