[PATCH] [LAA] Merge memchecks for accesses separated by a constant offset

[silviu.baranga at arm.com]

Constrain grouping algorithm to only merge pointers with maximum distance of 512.
This stops a (pottential) 20% regression in TSVC/Symbolics-flt. Added a regression test for this.

Remove redundant 'struct' keyword, renamed group iterator to 'Group'.
Update tests to fully match lines with CHECK-NEXT.
