RFR: 8287223: C1: Inlining attempt through MH::invokeBasic() with null receiver [v3]

[Vladimir Ivanov]

> Inlining attempt through `MH::invokeBasic()` when receiver is null. It triggers an assert when attempting to extract a `Method*` from a null constant.
> 
> Proposed fix bails out inlining attempt when receiver is null constant.
> 
> C2 has a similar issue, but the particular bytecode shape of `MH::invokeExact()` invoker hides the bug (dominating `MH::type()` call involves a null check and problematic call isn't compiled at all).  
> 
> Testing: hs-tier1 - hs-tier4
