* generic/tclExecute.c (TclExecuteByteCode): reorganised TEBC
automatic variables, defining them in tight blocks instead of at
the function level. This has three purposes:
- it simplifies the analysis of individual instructions
- it is preliminary work to the non-recursive engine
- it allows a better register allocation by the optimiser; under
gcc3.3, this results in up to 10% runtime in some tests
