0cedf0d13a Fix a bunch of mis-uses of an expressions's value.
The value field really should be treated as constant.

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

aa72f263ec Use an extra temp for v6 float modulo.
It seems the dag creation algorithm doesn't like "a = a op a", so use
"b = a op a" instead. Since I plan on fixing temp leaks anyway, this won't
be a problem (also, few people even use qfcc's v6 float modulo :P).

c96718493a A bit of a cleanup before fixing class type defs.
All internal structs now have "proper" names, and fit the naming convention
(eg, obj_module (like objective-c's types, but obj instead of objc). Some
redundant types got removed (holdovers from before proper struct tag
handling).

Also, it has proven to be unnecessary to build internal classes, so
make_class and make_class_struct are gone, too.

96110a0f54 Treat messages to id and Class separately.
As id and Class do not point to real objects as such, trying to get the
class from their types doesn't work, so instead send the message to a
"null" class that skips the method checks.

86091856be Revamp the static class creation.
Type names are cleaned up, as is the creation. Also, the class pointer in
the type encoding now gets emitted. However, Still need to actually create
_OBJ_CLASS_Class and fix the type encoding reloc handling in the linker.

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.

27b83a8d65 Clean up all extra aborts, using internal_error instead.
Some internal_error calls have no message, but at least things will be more
consistent.

Lots of trailing whitespace and otherwise blank lines.

78a9ba2557 Make expression alias chains not-a-bug.
The common cause seems to be casting a cast (very common, and I'm not sure
just realiasing the expression would be right). It does't cause any harm
(particularly, it doesn't trigger alias def chains), so I won't worry about
it.

bc1b483525 Nuke the rcsid stuff.
It's pretty useless in git.

6ead583195 Ruamoko: Implement infinity.
The special token __INFINITY__, like __FILE__ and friends, will expand to
a floating-point expression containing a value the C compiler considers
infinite. Obviously, this assumes that the system has relatively modern
float hardware -- but if it doesn't, having Ruamoko be able to represent
float infinity is the least of your problems. :)

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.

237f11c472 Fix cast expressions.
Casting between ints and floats needs special treatment to get the
conversion operator, but other casts need to be aliases.

f1d9570dc8 Fix constant value type handling.
Rename immediate.[ch] to value.[ch] and clean up the mess.

Add convert_value() to convert the type of a value (only scalar types).

7198be5726 Treat entities a bit like structures in field_expr ().
Look in the entity field symbol table for the field before looking in the
normal symbol table. This allows entity fields to be accessed even when
the current scope has symbol of the same name. However, checking the
normal symbol table where there is no such field allows for field
variables when I get around to implementing them.
