Bug: DaoJIT seems deprecated (and can't compile)

[dumblob]

As discussed already quite some time ago, LLVM renamed JIT to MCJIT and started using another new JIT. DaoJIT is not up to date and compilation ends with the following:

g++ -O2 -DDAO_WITH_NUMARRAY -DDAO_WITH_THREAD -DDAO_WITH_CONCURRENT -DDAO_WITH_RESTART -DTARGET_PLAT=\"linux\" -DLINUX=2 -DUNIX=1 -I../../kernel/ -I../auxlib/ -fPIC -I/usr/include   -D_GNU_SOURCE -D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS -std=c++11 -fno-rtti -c daoJIT.cpp -o DaoMake.Objs/daoJIT.cpp.6DC2.o
daoJIT.cpp:41:38: fatal error: llvm/ExecutionEngine/JIT.h: No such file or directory
 #include "llvm/ExecutionEngine/JIT.h"
                                      ^
compilation terminated.

This module is of a high importance and thus shouldn't be abandoned.
