bytecode removal

[Jim Wilson]

You unfortunately missed a number of things that my patch handled correctly.
You can easily find all of the stuff you missed by using grep.  For instance:

find . -type f -exec grep -i bytecode \{\} \; -print

This shows that you left behind some unused global variables in expr.c, you
left behind a comment in stmt.c, and the VMS scripts make-cc1.com and
vmsconfig.com need to be fixed.

find . -type f -exec grep -i b\[ci\]\[_-\] \{\} \; -print

Various Makefile rules still need fixing.  config/msdos/top.sed,
config/vax/xm-vms.h, config/winnt/config-nt.sed, f/INSTALL, f/g77install.texi,
and objc/Make-lang.in all need fixes.
