This adds the jump slot mapping for LoongArch. This is a simple
change that ensures lldb running properly.
Note that this problem was found only when CMake variables
"DLLVM_ENABLE_ASSERTIONS=ON" is selected.
Without this patch,
$ build/bin/lldb test
../ELFHeader::GetRelocationJumpSlotType() const: Assertion `false &&
"architecture not supported"' fail
With this patch
$ build/bin/lldb test
(lldb) target create "test"
Current executable set to '../test' (loongarch64).
