LLVMJIT: Adapt to API changes in gdb and perf support.
During the work of upstreaming my previous patches for gdb and perfsupport the API changed. Adapt. Normally this wouldn't necessarily besomething to backpatch, but the previous API wasn't upstream, and atleast the gdb support is quite useful for debugging.Author: Andres FreundBackpatch: 11, where LLVM based JIT support was added.
