27ae5ccfce Fix ICE after incomplete type error
Attempting to define a variable with an incomplete type is an error, and
results in a default size 1 of allocated, but I forgot to set default
alignment when implementing alignment.

81293d98dd Fix qfo line info dumping
The addition of xdef data has made qfo_to_progs unusable in qfprogs,
resulting in various invalid memory accesses. It always was an ugly hack
anyway, so this is the first step to proper qfo support in qfprogs.

81083698a8 Move to using an in-memory form of ddef_t
This allows the VM to work with extended ddefs transparently. It seems

4df926e531 Write extended ddef information to progs far data
I was originally going to put it in the debug syms file, but I realized
that the data persistence code would need access to both def type and
certainly correct def offsets for defs in far data.

caf78b5422 Rename ty_none to ty_basic
This far better reflects the actual meaning. It is very likely that
ty_none is a holdover from long before there was full type encoding and
it meant that the union in qfcc's type_t had no data. This is still
true for basic types, but only if not a function, field or pointer type.
If the type was function, field or pointer, it was not true, so it was
misnamed pretty much from the start.

a6003ed08a Walk qfo alias chain for type size and alignment
While the basic type is stored in the alias type record, it's no good
for size or alignment as it will give incorrect results for complex

6a70d2e362 Give alias types a unique encoding
The encoding is used as the def name and it needs to be different than
the alias target or the linker throws it away as an external def.

4c40928112 Remove what appears to be a redundant check
It was long wrong anyway as it checked past the end of the function's

7a399c956b Encode function parameter alignment
The encoding is 3:5 giving 3 bits for alignment (log2) and 5 bits for
size, with alignment in the 3 most significant bits. This keeps the
format backwards compatible as until doubles were added, all types were
aligned to 1 word which gets encoded as 0, and the size is unaffected.

1985b6d4fd Avoid creating a struct temp for ivar struct return
This fixed the uninitialized temp warning in HUD.r. The problem was
caused by the flow analyzer not being able to detect that the struct
temp was being initialized by the move statement due to the address of
the temp being in a pointer temp. While it would be good to use a
constant pointer for the address of the struct temp or improving the
flow analyzer to track actual data, avoiding the temp in the first place
results in nicer code as it removes a move statement.

3e651b43f8 Handle aliased values when emitting statements
With this, cast address initializers work. I have to wonder if the alias

7dc1a0640a Delay creating actual enum symbols
