[test] Use -passes syntax in Analysis tests

Another step towards getting rid of dependencies to the legacy
pass manager.

Primary change here is to just do -passes=foo instead of -foo in
simple situations (when running a single pass). But also
updated a few test running multiple passes.

[knownbits] Preserve known bits for small shift recurrences

The motivation for this is that I'm looking at an example that uses shifts as induction variables. There's lots of other omissions, but one of the first I noticed is that we can't compute tight known bits. (This indirectly causes SCEV's range analysis to produce very poor results as well.)
