Fix loading structs into params via an offset pointer.
...
For certain values of "fix" :/. The code is ugly, but it does the right
thing: calculate the effect address and use the resulting pointer in a
move instruction.

Put another bandaid on the type creation system.
...
It seems that building types is very fragile: all too easy to fix things
in one place and break something somewhere else. I guess the type system
will need a comlete rewrite at some stage.

And fix build_struct for built-in struct types.
...
The previous fix broke builtin structs (eg, @param). Calling find_type()
for built-in structs has proven to be a bad idea :)

Make struct decls actually work.
...
find_type() does type comparisons based on tag name for struct/union/enum
but when it returns the previous tag (eg, from "struct foo;") the returned
type has a null symtab pointer, so setting the symtab pointer in the type
before calling find_type() only throws away the symtab. Thus, since
find_type() doesn't check the symtab pointer when comparing the types, set
the symtab pointer after calling find_type().

These really need to be alias expressions rather than cast expressions
so the two can be separated as cast expressions should not be lvalues.

Allow qc style function params.
...
Due to ambiguities in the grammar, qc-style function params and c-style
function params had to be completely separated. This means that qc-style
functions can not use pointers and must use qc-style function declarations
for parameters, and c-style functions must use c-style param declarations.
While this rule is tedious for converting the Ruamoko library, it does
actually make for a more consistent language.
