Hi.

I try to pick the code for testing the performance. However, I found the new dwarflinker-next, will crash at some specify code path

See crash stacktrace here:

F23924676: screenshot-20220727-192355.png <https://reviews.llvm.org/F23924676>

I try to debug and found the reason:

during analysis stage, `NamesGenerator.assignName(CU, DieIdx)` can not assign a valid name for some unhandled DIEEntry tag, like

+ `DW_TAG_thrown_type`

This will cause the final `CU.TypeInfo.TypeName` be null, and crash at the `TypePool.insert` during ODR stage

Any solution for this ? Should we just mark it as `bad type` with the raw hex ?  Or add some more handle cases ?
