Vyacheslav Egorov 50736d2bd9 [vm/compiler] Avoid redundant moves in linearscan
When resolving control flow check detect a case when all
predecessors would contain the same move and try to
emit this move at the entry to the block if possible
(i.e. when the source of the move is not destroyed by other
moves at predecessors).

Optimization discovered as part of go/dart-llvm-assessment
