code/bit-bash.lisp::
 Add {{{BYTE-BASH-COPY}}} for copying bytes

code/exports.lisp::
 Add {{{BYTE-BASH-COPY}}}

compiler/generic/vm-fndb.lisp::
 Add {{{BYTE-BASH-COPY}}}

compiler/generic/vm-tran.lisp::
 Call {{{BYTE-BASH-COPY}}} in the deftransform for {{{REPLACE}}}.

Check that the start and end indices make sense for the given
strings.  This is important before we start bashing random parts of
the string, potentially overwriting other objects.

This fixes the immediate issue, but there are still problems with
very long strings.  The bit-index for such strings won't fit in an
(unsigned-byte 32).

vm-fndb.lisp:
o Correct the defknown to have the correct arg types (vm::offset
  instead of index).

vm-tran.lisp:
o Update deftransform to use vm::offset instead of index.

Config.sparc_common:
o Enable ASSEM_SRC, ARCH_SRC, OS_SRC, OS_LIBS again

Config.sparc_gcc:
o Don't use -traditional-cpp when creating dependencies because that
  causes the old (varargs.h) version of va_start to be used instead of
  the stdard.h version we want.

Config.sparc_sunc:
o Remove ASSEM_SRC, ARCH_SRC, OS_SRC, OS_LINK_FLAGS, and OS_LIBS since
  they're in Config.sparc_common.

to read a file will cause it to be compiled, which isn't quite what we
wanted.

   * Boot file for building the release with a new fasl version.

versions are untested.

print.c:
 * Use utf16_output to output strings as utf8 instead of raw utf16. 

interr.c:
 * Make utf16_output public instead of static.

interr.h:
 * Declare utf16_output.

 * Didn't finish the solaris split in previous commit, so finish it
   now.
 * Split out FreeBSD, NetBSD, and OpenBSD into new files.

src/lisp/x86-validate.h:
o Remove linux, darwin, and solaris parts

src/lisp/x86-validate-linux.h:
src/lisp/x86-validate-darwin.h:
src/lisp/x86-validate-solaris.h:
o New files for each os.

 * Get rid of the RCS Header stuff.  They're meaningless in git.
 * Add public domain comment to some of the files if the only comment
   was the RCS header.

followed by low; anything else is invalid.

No more random NUL ASCII characters on output now.

have special treatment in the compiler anymore.

o Convert x/n to x*(1/n) when n is a power of two since 1/n has an
  exact representation.
o Convert 2*x to x+x.
