  [SLP]Fix loads sorting for loads from diffrent basic blocks

Patch fixes lookup for loads from different basic blocks. Originally,
the code checked is the main key (combined with parent basic block) was
created, but did not include the key into LoadsMap. When the code looked for
the load pointer in LoadsMap, it skipped check for parent basic block
and could mix loads from different basic blocks (but the same underlying
pointer). Currently, it does lead to any issues, since later the code
compares parent basic blocks and sorts loads properly. But it increases
compile time and affects compile time.
