RFR: 8351778: JIT compiler fails when running -XX:AOTMode=create

[Ioi Lam]

Since [JDK-8348426](https://bugs.openjdk.org/browse/JDK-8348426), `SymbolTable::_shared_table` is corrupted inside the `VM_PopulateDumpSharedSpace` safepoint. Afterwards, the JIT will fail to look up classes/fields/etc, resulting in various mysterious crashes.

The fix is to use a separate table for dumping.
