More efficient Merge implementation. (#486) 
Avoid a tree of merge objects, which can result in
what I suspect is n^2 calls to Seek when using Without.

With 100k metrics, and a regex of ^$ in BenchmarkHeadPostingForMatchers:

Before:
BenchmarkHeadPostingForMatchers-8              1        51633185216 ns/op      29745528 B/op      200357 allocs/op

After:
BenchmarkHeadPostingForMatchers-8             10         108924996 ns/op 25715025 B/op     101748 allocs/op

Brian Brazil 407e12d051 Make MemPostings nested.
