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.

Fix incorrect placement of far data

Align local and far data spaces
...
I plan on adding doubles, and so it's necessary to ensure that attempts
to align doubles in local or far data spaces remain aligned after final
linking.

Rename qfot_type_t.ty to meta
...
When I did up a ruamoko implementation of a type encoding dumper, I
named the field meta, which feels much better than ty.

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).

It is necessary to know if a def is a function parameter so it can be

Fix class type encoding.
...
First, the class def needed to be created before the class type, then the
def space indices had to be set early, otherwise the relocs wound up with
space 0 instead of the correct space.

Make the type encodings findable.
...
The base of the type encodings block is given by the .type_encodings def.
The block begins with a "null" type (4 words of 0), followed by the first
type encoding.
At some stage, I will need to add information for extended def information
(32 bit offset, type encoding, other?), but this is good for initial
testing.
