61f84a2cdc gc: shuffle #includes 
#include "go.h" (or "gg.h")

becomes

#include <u.h>
#include <libc.h>
#include "go.h"

so that go.y can #include <stdio.h>
after <u.h> but before "go.h".
This is necessary on Plan 9.

2ad42a8249 gc: frame compaction for arm. 
Required moving some parts of gc/pgen.c to ?g/ggen.c

on linux tests pass for all 3 architectures, and
frames are actually compacted (diagnostic code for
that has been removed from the CL).

e7a0f67603 gc: introduce explicit alignments 
No semantic changes here, but working
toward being able to align structs based
on the maximum alignment of the fields
inside instead of having a fixed alignment

758f2bc556 eliminate the package global name space assumption in object files 
5g/6g/8g: add import statements to export metadata, mapping package path to package name.
	recognize "" as the path of the package in export metadata.
	use "" as the path of the package in object symbol names.

5c/6c/8c, 5a/6a/8a: rewrite leading . to "". so that ·Sin means Sin in this package.

5l/6l/8l: rewrite "" in symbol names as object files are read.

gotest: handle new symbol names.

gopack: handle new import lines in export metadata.

Collectively, these changes eliminate the assumption of a global
name space in the object file formats.  Higher level pieces such as
reflect and the computation of type hashes still depend on the
assumption; we're not done yet.
