- Turn on runtime detection of loop and jump alignment as Aranym people

reported they got some improvement with it and larger loops. Small
loops are an issue for now until unrolling is implemented for DBcc.
- Const jumps are identified in readcpu. I don't want to duplicate code
uselessly. Rather, it's the JIT job to know whether we are doing block
inlining and un-marking those instructions as end-of-block.

- 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.
