Give __obj_exec_class a sterner beating.
...
When linking a def into a defspace, ensure it can be removed. This fixes
the missing __obj_exec_class def in qwaq.

Remove the dirty hack used for accessing params and the return value.
...
Instead of using the equivalent of *(float*)&.return, now use the
equivalent of (float).return. No conversion is done in the "cast".
NOTE: this sort of cast should be separated from normal casts.

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.

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.
