RFR: 8279822: CI: Constant pool entries in error state are not supported [v2]

[Vladimir Ivanov]

> Compiler interface doesn't expect to see constant pool entries in error state and crashes when those are encountered.
> 
> JDK-8262377 improved handling of class constants in error state (`JVM_CONSTANT_UnresolvedClassInError`), but there were more cases left unnoticed (`CONSTANT_MethodHandle`, `CONSTANT_MethodType`, and `CONSTANT_Dynamic`). 
> 
> Proposed fix introduces proper support in CI of unresolved constants in error state and improves handling of such cases in C1/C2.
> 
> Also,  for `CONSTANT_MethodHandle` it turned out that some of `LinkageError`s don't transition relevant CP entry into error state (leaving it in unresolved state forever). The fix addresses it.
> 
> Testing: hs-tier1 - hs-tier6
