d1e83b9d48 [qfcc] Create a compound initializer expression type 
This fixes the problem of using the return value of a function as an
element in a compound initializer. The cause of the problem is that
compound initializers were represented by block expressions, but
function calls are contained within block expressions, so def
initialization saw the block expression and thought it was a nested
compound initializer.

Technically, it was a bug in the nested element parsing code in that it
wasn't checking the result value of the block expression, but using a
whole new expression type makes things much cleaner and the work done
paves the way for labeled initializers and compound assignments.

393e540ffa [qfcc] Print the source name of an undefined label 
Undefined labels generated by the compiler indicate severe trouble.

1cd5ea5732 [qfcc] Add support for named labels in statements 
Yeah, I've finally decided to implement goto. Limited to function scope
of course.

9acfdea8b5 [qfcc] Improve line number binding for function calls 
Multi-line calls (especially messages) got rather confusing to read as
the lines jumped back and forth. Now the binding is better but the dags
code is reordering the parameters sometimes.

e23aa40994 Implicitly cast unadorned floating point constants 
Floating point constants without f or d adornments will automatically
cast, without warnings, to the type appropriate to the rest of the
expression.

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.

aaab18c9a7 Nuke a dead field. 
It looks like ex_temp_t.expr was never really used, and I have no idea
what I had intended (not surprising after ~17 years).

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.

7a7a685105 Add support for actual vector expressions. 
Currently, they can represent either vectors or quaternions, and the
quaternions can be in either [s, v] form or [w, x, y, z] form.

Many things will not actual work yet as the vector expression needs to be
converted into the appropriate form for assigning the elements to the
components of the "vector" type.

a6cdc8735a Start implementing vec = [x,y,z]. 
This is a nice feature found in fteqcc (also a bit of a challenge from
Spike). Getting bison to accept the new expression required rewriting the
state expression grammar, so this is mostly for the state expression. A
test to ensure the state expression doesn't break is included.

cef2136050 Implement "not" logic for while and do-while. 
This goes towards complementing the "if not" logic extension. I need to
check if fteqcc supports "not" with "while" (the version I have access to
at the moment does not), and also whether it would be good  to support
"not" with "for", and if so, what form the syntax should take.

8d34d33055 Implement "if not (foo)" syntax. 
It is syntactic sugar for if (!(foo)), but is useful for avoiding
inconsistencies between such things as if (string) and if (!string), even
though qcc can't parse if not (string). It also makes for easier to read
code when the logic in the condition is complex.

As each value is now unique, their labels can also be unique, which will
improve CSE.
