[jdk25u-dev] RFR: 8370939: C2: SIGSEGV in SafePointNode::verify_input when processing MH call from Compile::process_late_inline_calls_no_inline()

[Aleksey Shipilev]

We have seen Netty folks stepping on this bug, as well as some customers. 

Additional testing:
 - [x] One external user have tested the 25u-dev with this patch applied in their canary deployment with apparent success
 - [x] Linux x86_64 server fastdebug, new regression test fails without the fix, passes with it
 - [x] Linux x86_64 server fastdebug, `hotspot_compiler`
 - [ ] Linux x86_64 server fastdebug, `all`
