Is related to CORE5110

Bug CORE5110 was fixed using first (simple) way from choices below:

1. ignore no_gc flag in VIO_get_current() and backout dead record version, or

2. make VIO_get_current() to reconstruct previous record version (which will
be placed over currently dead primary record version).

Second way could be more efficient but more complex to implement
