* generic/tclInt.h: Added function prototypes for
TclCompileStringCmd and TclCompileReturnCmd.
* generic/tclCompile.h: Added definition of INST_STRLEN opcode and
updated LAST_INST_OPCODE value.
* generic/tclBasic.c: Added information about TclCompileStringCmd
and TclCompileReturnCmd to BuiltInCmds table.
* generic/tclExecute.c (TclExecuteByteCode): Added support for the
INST_STRLEN opcode.
* generic/tclCompCmds.c
(TclCompileStringCmd): Basic implementation of byte-compiled
[string] command. Not all subcommands are implemented; those
that are not an out-line compiled.
(TclCompileReturnCmd): Byte-compiled implementation of [return]
command. Only "simple" returns are byte-compiled; in particular,
if the -code, -errorinfo or -errorcode flags are used, the command
is not byte-compiled.
