Bootstrap the none.gc.debug grade using MSVC as the C compiler.
compiler/c_util.m:
Avoid a limitation in MSVC where string literals are not allowed
to be longer then 2048 chars.
Error C2026 is now avoided by instead of outputing a string as
"a very long string" chunk it up into "a very " "long string"
where each chunk is 512 characters long.
Redefine c_util__output_quoted_string to call
c_util__output_quoted_multi_string, so as to avoid some code
duplication.
compiler/llds_out.m:
The definitions of any types used in the module need to be
output before they are used, so output them first.

Add support for generation of builtins to the MLDS backend.
compiler/ml_code_gen.m:
Add support for generating builtins (mostly copied
from call_gen.m and code_util.m, but with a few
changes).
compiler/code_util.m:
Add a comment warning about the code duplication.
compiler/c_util.m:
compiler/llds_out.m:
compiler/mlds_to_c.m:
Move (most of) the code from llds_out__binary_op_to_string
into a new routine c_util__binary_infix_op/2, and change
llds_out.m and mlds_to_c.m to use it.
compiler/mlds_to_c.m:
(An unrelated change:)
Don't output any comments for "public" access,
since such comments end up being just noise.

A batch of changes related to the development of the new MLDS back-end.
compiler/notes/compiler_design.html:
Reorganize the documentation to reflect the multi-target /
multiple back-end nature of the compiler.
Document mlds.m and the new modules c_util.m and mlds_to_c.m.
compiler/mlds_to_c.m:
New module. This converts MLDS to C/C++ code.
This version compiles, but it is still quite incomplete;
there's lots of parts which are still not yet implemented.
compiler/llds_out.m:
compiler/c_util.m:
Move some procedures from llds_out.m into a new module c_util.m,
so that they can also be used by mlds_to_c.m.
compiler/mlds.m:
- Add new functions for use by mlds_to_c.m:
* get_prog_context/1, for getting the prog_context from an
mlds__context
* get_module_name/1, for getting the module name from the mlds
* module_name_to_sym_name/1, for converting an mlds_module_name
to a sym_name
- Change the mlds__func_signature type to
* allow multiple return values, for consistency with the
MLDS `return' statement;
* include the names of the parameters.
- Undo the premature over-optimization of making the `constness'
and `finality' flags share the same flag bit.
