Optimisations for INST_START_CMD [Bug 926164].
* generic/tclCompile.c (TclCompileScript): avoid emitting
INST_START_CMD as the first instruction in a bytecoded Tcl_Obj. It
is not needed, as the checks are done before calling TEBC.
* generic/tclExecute.c (TclExecuteByteCode): runtime peephole
optimisation: check at INST_POP if the next instruction is
INST_START_CMD, in which case we fall through.
