  Log Message:
  -----------
  gc: fix inf Memory_Block prologs, add -D traces

inf gc did not store string/pmc Memory_Block prologs (see pobj.h),
and Parrot_str_copy changed a Buffer_flag, i.e. the str->encoding
from the prev. string.
waste now more space in inf for these prologs.

All gc's are now pretty stable.
Fixes #1136 mostly, but not 100% yet.
