RFR: 8315954: getArgumentValues002.java fails on Graal [v3]

[Doug Simon]

> This PR adds `HotSpotResolvedJavaMethod.getOopMapAt` to get the oop map for a method at a given BCI. This is required to do correct clearing of oops at OSR entry points.
> 
> As part of this addition, I needed to be able to detect requests for oop maps at invalid BCIs. For this, I added `InterpreterOopMap::has_valid_mask()`. When an oop map computation is requested for an invalid BCI, this method returns false.

Doug Simon has updated the pull request incrementally with one additional commit since the last revision:

  add assertion to InterpreterOopMap::resource_copy
