adeef4a4eb Copy named expressions.
Since expressions can be modified, making DAGs this early causes
corruption of the expression tree.

a43946abf3 Give short values special treatment.
As a short value fits directly into a statement, it needs a fake def that
holds its value in the def's offset in order for the value to be written to
the statement.

1b8edc07c9 Adjust the offsets of ivars in derived classes.
As ivar structs are not independent, their starting offset is not
necessarily zero (almost never will be for derived classes).

d66a441867 Write out the far data space as well as the near.
This causes the Objective-QC structs to be emitted now that they havve been
moved to the far data space. Relocs are broken, though.

59a683d39e Protect the name passed into emit_struct().
The name passed into emit_struct is sometimes created via va(), but the
struct creation code also uses va. This makes a mess of names.

81125cff3a Creation of .ctor now mostly works.
There seems to be problems with the actual code generation using incorrect
addresses, but a very simple test file compiles successfully.

da14c95bb8 Initialize current_symtab in class_init() when necessary.
If an objective-qc symbol is the first token to be read, class_init() is
called before the parser gets a chance to perform the initialization
action. However, class_init() setting current_symtab if the first
objective-qc symbol is seen in a function body would be bad.

b629c12b31 Do not change the type of the return operand.

d54a96e68a Make enum values visible.
Put them in the current symbol table as well as the enum symbol table. The

7b22bfba63 Better Objective-QC keyword detection.
Use a flag in the keyword struct rather than checking for "@" in the

993bee4f59 Do not count unimplemented methods.
The method emitter skips unimplemented methods, so counting them when
figuring out how many methods to emit leads to a segfault.

2203903bb2 Temporarily splice the class's ivar chain into the symbol table.
The root class's ivar symbol table needs to be connected to the global

d12cdca758 Functions and enums now seem to be working properly.
find_type now operates recursively (depth-first) so built up typechains

@overload is treated as a specifier (directly as a storage class, similaar
to typedef).
