[clang] [clang-repl] Resolve mapper symbols via lookupAndApply (PR #223383)

[Lang Hames via cfe-commits]

https://github.com/lhames created https://github.com/llvm/llvm-project/pull/223383

IncrementalExecutor's createSharedMemoryManager resolved the SharedMemoryMapper instance and wrapper addresses with EPC.getBootstrapSymbols. For consistency, switch to lookupAndApply/recordAddr on the bootstrap JITDylib instead.

Subject: [PATCH] [clang-repl] Resolve mapper symbols via lookupAndApply

IncrementalExecutor's createSharedMemoryManager resolved the
SharedMemoryMapper instance and wrapper addresses with
EPC.getBootstrapSymbols. For consistency, switch to
lookupAndApply/recordAddr on the bootstrap JITDylib instead.
