SLPVectorizer: limit the number of alias checks to reduce the runtime.

Description

SLPVectorizer: limit the number of alias checks to reduce the runtime.

In case of blocks with many memory-accessing instructions, alias checking can take lot of time
(because calculating the memory dependencies has quadratic complexity).
I chose a limit which resulted in no changes when running the benchmarks.
