Branch:
https://github.com/tarantool/tarantool/tree/np/gh-5107-dont-squash-ops

@ChangeLog:
 - Rework upsert operation in vinyl so that now (gh-5107):
   - if upsert can't be applied it is skipped and corresponding error is logged (gh-1622);
   - upserts now follow associative property: result of several upserts
     doesn't depend on the order of their application (gh-5105);
   - upserts referring to -1 fieldno are handled correctly now (gh-5087).
   - there's no more upserts squash procedure: upserts referring to the
     same field with arithmetic operations are not merged into one 
     operation since resulting upsert might not be applied - as a result
     both upserts would be ignored (meanwhile only one should be).

Changes in v3:
 - Removed upsert squashing procedure;
 - Added two additional test covering overflow error during upsert
   application;
 - Fixed NULL dereference bug in vy_apply_upsert_on_terminal_stmt().
