37dac186a8 Ruby: String.try_convert isn't value-preserving 
`String.try_convert` can convert arbitrary objects to strings, which
obviously isn't value-preserving.

1240c11c4b Ruby: parse some string literals as regex 
In addition to regex literals, also parse normal string literals
as regular expressions if they somehow "flow" into a method call
that is known to interpret string values as regular expressions.

fc351fbd64 Ruby: Remove value-flow for name-matched summaries 
String summaries that are identified by name only should not specify
value-preserving flow as this can cause spurious flow in cases where
they are applied to different but identically-named methods.
