* tests/compile.test: added compile-11.* interp result checks

	* generic/tclUtil.c (TclGetIntForIndex): added Tcl_ResetResult
	before Tcl_AppendStringsToObj to prevent shared object crash when
	called from bcc instruction.  The Tcl_Append* calls that append to
	the result object that are invoked by bcc insts must remember to
	call Tcl_ResetResult because the bcc doesn't do this for us.
	[Bug #456892]
