Do translate FMUL instructions, the core needs to be fixed and this is
...
not translation of that instruction. I believe this is related to some
misgeneration of FPU core sequence and allocation of FP registers?

- Remove dead code in readcpu.cpp concerning CONST_JUMP control flow.
...
- Replace unused fl_compiled with fl_const_jump
- Implement block inlining enabled with USE_INLINING && USE_CHECKSUM_INFO.
However, this is currently disabled as it doesn't give much and exhibits
even more a cache/code generation problem with FPU JIT compiled code.
- Actual checksum values are now integral part of a blockinfo regardless
of USE_CHECKSUM_INFO is set or not. Reduce number of elements in that
structure and speeds up a little calculation of checksum of chained blocks.
- Don't care about show_checksum() for now.
