RFR: 8272573: Redundant unique_concrete_method_4 dependencies [v2]

[Vladimir Ivanov]

> Equivalence checks in `Dependencies::assert_common_4()` are too strong which leads to `unique_concrete_method_4` dependencies being repeatedly recorded and duplicating nmethod dependencies registered.
> 
> The underlying problem is `note_dep_seen()` mutates internal bitmap, but the nested checks fail fast.
> So, multiple requests are required to populate the bit-map for all the arguments in order to make the detection of duplicate assertions work. And it leads to duplicate dependencies registered.
> 
> It turns out `call_site_target_value` is also affected in a similar manner (see `Dependencies::assert_common_2` for dependencies without explicit context argument), so I fix it along the way.
> 
> Testing: hs-tier1 - hs-tier6
