Various bits of cleanup, efficiencies, and comment documentation in tclVar.c

better comments
merge trunk
even better ... or so I hope: also inlining INST_PUSH1 in the peephole, checking for ISC after LOAD1 and PUSH1

Put back TclBackgroundException in internal stub table, so extensions using this, compiled against 8.5 headers still run in Tcl 8.6.
If TCL_NO_DEPRECATED is defined, make sure that TIP #139 functions all are taken from the public stub table, even if the inclusion is through tclInt.h.
