As discussed in the recent Mercury meeting, remove support for the GCC backend.
It was very much out of date and supporting it proprerly would means having to
track changes to GCC's internals. Furthermore, its presence complicates
building the compiler.
The main thing this change does not address is the fact that we invoke
the compiler through C code, e.g. main.c in the top-level of the source
tree. This was required by the GCC backend and can now be removed, but
I will do that as a separate change.

compiler/gcc.m:
compiler/maybe_mlds_to_gcc.pp:
compiler/mlds_to_gcc.m:
Delete the files containing the GCC backend.
compiler/options.m:
compiler/handle_options.m:
Delete support for `--target asm' and `--pic'.
(The latter was only used by the GCC backend.)
compiler/*.m:
doc/user_guide.texi:
compiler/notes/comiler_design.html:
compiler/notes/work_in_progress.m:
Conform to the above change.

% The MLDS back-end.

|
|
% This package includes
|
|
% - the MLDS data structure, which is an abstract
|
|
% representation of a generic imperative language;
|
|
% - the MLDS code generator, which converts HLDS to MLDS;
|
|
% - the high-level C back-end, the Java back-end, the .NET back-end,
|
|
% and a wrapper for the assembler back-end,
|
|
% each of which convert MLDS to their respective target language.
|
|
%
|
|
% The main part of the assembler back-end, which converts MLDS to GCC's
|
|
% internal abstract syntax trees and then invokes the GCC back-end to convert
|
|
% this to assembler, is in a package of its own, so that this package doesn't
|
|
% depend on the GCC back-end.
