Allocate LSEVisitor on the arena stack.

Use a simple wrapper to allocate the LSEVisitor on the arena
stack. This allows adding additional members to the class
without running into stack frame size errors with clang.

Make the pre-allocated buffer for `store_records_` a member
of LSEVisitor as originally intended.
