[qfcc] Rearrange type initialization
...
Fixes #6
It turned out that the problem with @zero was caused by initial type
chaining occurring before the structures had been initialized and thus
the linker's @zero type encoding string was incorrect: {?=} instead of
{tag @zero-}, thus when the actual type encoding supplied by an object
file came along (with the correct encoding string), it wasn't found.

[qfcc] Rework QuakeC function type manging

It is now "consistent" with the rest of the type building in that it
uses find_type(append_type(return, params)) like the C version, thus

overload test.

its abuse of the type system.

[qfcc] Implement type aliasing again
...
When a type is aliased, the alias has two type chains: the simple type
chain with all other aliases stripped, and the full type chain. There
are still plenty of bugs in it, but having the clean type chain takes
care of the major issue that was in the previous attempt as only the
head of the type-chain needs to be skipped for type comparison.
Most of the bugs are in finding the locations where the head needs to be
skipped.

While a block expression's result may be an l-value, block expressions
are not (and their results may not be), thus taking the address of one

the assignment code when dealing with structures.
