[NFC] LocalGraph: Optimize params with no sets (#6046)
If a local index has no sets, then all gets of that index read from the entry block
(a param, or a zero for a local). This is actually a common case, where a param
has no other set, and so it is worth optimizing, which this PR does by avoiding
any flowing operation at all for that index: we just skip and write the entry block
as the source of information for such gets.
#6042 on precompute-propagate goes from 3 minutes to 2 seconds with this (!).
But that testcase is rather special in that it is a huge function with many, many
gets in it, so the overhead we remove is very noticeable there.
