added enum names and bumped to 256 - 128.
added explanation.

changed a few mal() (garbage-collected) to
malloc()/free() (manually collected).

this is similar to the assemblers including ../cc/lexbody
and ../cc/macbody.

* hook go-specific loader code into 8l.

* make current 8.out.h and 6.out.h backward compatible
with plan 9's versions.  i had added some constants in
the middle of enums and have now moved them to the end.
this keeps us from invalidating old .8 and .6 files.
not sure how much it really matters, but easy to do.

type of the field.  Use the field alignment to compute the
size of a structure.

This may help 8g but is mainly for gccgo.  gccgo maintains the
standard C/C++ ABI for structure field alignment.  For the
i386, this requires that a float64 field in a struct be
aligned on a 32-bit boundary, although for efficiency a
variable of type float64 or []float64 should be aligned on a
64-bit boundary.

I also removed the unused size field from structField.

- astprinter: will subsume ast printing functionality of printer
- docprinter: will subsume doc printing functionality of printer
        also: more logic to collect all the documentation pertaining
	      to all files of a package
- parser: some cleanups, stricter syntax checks

- much better tracing output
- many more checks (still permits more than just syntactically legal

- updated with respect to updated AST
- general cleanup throughout
