fa482e8ee5 [qfcc] Give address expressions their own type
Definitely a pain to get working after the switch, but definitely worth
the effort. Still exposing type aliasing bugs.

23c9a317f8 [qfcc] Give alias expressions their own type
While this was a pain to get working, that pain only went to prove the
value of using proper "types" (even if only an enum) for different
expression types: just finding all the places to edit was a chore, and
easy to make mistakes (forgetting bits here and there).

Strangely enough, this exposed a pile of *type* aliasing bugs (next
commit).

c9b2a740a0 [gamecode] Add etypes for long and ulong
And partial implementations in qfcc (most places will generate an
internal error (not implemented) or segfault, but some low-hanging fruit
has already been implemented).

6d5ffa9f8e [build] Move to non-recursive make
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.

The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.

Most of the old Makefile.am files  are now Makemodule.am.  This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases).  The current remaining Makefile.am files are for
standalone sub-projects.a

The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.

While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).

ab3d91f0c3 [qfcc] Clean up simple type checking
All simple type checks are now done using is_* helper functions. This
will help hide the implementation details of the type system from the
rest of the compiler (especially the changes needed for type aliasing).

4c6e1b7fc4 [qfcc] Fix some uninitialized variable warnings
I really wish gcc would catch more issues when not optimizing.

d150210888 [qfcc] Nuke PAS from orbit
And there was much rejoicing. I hated having to create that opcode.

ea3af84baa Fix ICE when const-folding doubles

df7c08a010 Add support for doubles to Ruamoko
Only as scalars, I still need to think about what to do for vectors and
quaternions due to param size issues. Also, doubles are not yet
guaranteed to be correctly aligned.

fa69aeef0f Improve handling of temp aliases
This makes all tests pass when not optimizing. More work needs to be
done in dags.

3196bcc851 Allow fold_constants to handle some math identities

b7b6a89b91 Simplify fold_constants
While this does break automatic type promotion, it does stop
fold_constants recursing through complex expressions: only the top level
expression needs to be folded, and then only if both sides are actually
constant.

f58c2fef5a Switch QF's quaterions from wxyz to xyzw.
After messing with SIMD stuff for a little, I think I now understand why
the industry went with xyzw instead of the mathematical wxyz. Anyway, this
will make for less pain in the future (assuming I got everything).

34bcf7faab Do a pure/const/noreturn/format attribute pass.
I always wanted these, but as gcc now provides warnings for functions that
could do with such attributes, finding all the functions is much easier.

6eb6b6c0ba Change pointer_t to unsigned and clean up the mess.
It doesn't make sense to have negative pointers. The size of the commit is
from enabling gcc's -Wtype-limits warning and cleaning up that mess too.

732d6a1520 Provide emulation for vector / float and quaternion / float.
The VM doesn't have such instructions, so emulate them via
vector * (1 / float) and quaternion * (1 / float).

28ce35f1c1 Make values independent objects.
values are now uniquely allocated (for the current object file). With
this, constants in dags will work.

9095e1eabc Rework build_switch to use initialize_def.
This required support for label reference expressions, whose purpose is to
represent the address of a label.

Only pointer +/- integral is supported. pointer - pointer will come later.

55cc0f9206 Bring back the unsigned type (PROGS version bump)
This is only low-level support (the unsigned keyword still does not work),
but sufficient to make switch statements using jump tables work.

52b561f7cb Nuke bind expressions.
Since I'm planning on implementing CSE and other optimizations, they're
rather redundant (and I'm having trouble getting them to work).

f8cc347dce Print expressions as dot files.
While the resulting images can be a little confusing, they're much easier
to read than my cryptic postfix notation.

5b43fc1de3 Improve interaction between temps and const_folding.
Unfortunately, this seems to overdo the decrementing, so it could be
dangerous, but the ruamoko directory builds properly.
