Change the representation of VTSs. Instead of using an XArray of
ScalarTSs, have the ScalarTS array as a trailing array directly on the
VTS structure. This reduces the number of malloc'd blocks per VTS
from 3 to 1, since an XArray always requires 2 malloc'd blocks. At
least for tc19_shadowmem this reduces the total amount of heap
turnover in Arena 'tool' by a factor of 3, and modestly improves
performance whilst modestly reducing overall memory use.
