7f25485fc6 go/printer: 
- printing of expressions: put spaces only where "needed"
- printing of import statements: no double indentation if there are no renames
- print labels on separate lines
- added extra test files

go/ast:
- unified basic literal nodes and as a result deleted duplicated code
- added initial code to track scopes (not fully used yet)

replaces CL 34553

58c5e62f8b better gofmt formatting: 
- first cut a better line breaks in expr lists
- trailing commas and semis printed where we tend to write them
- fixed a couple of minor spacing issues (interface{}, chan<-, map[x]y, x: y)
- removed some formatting flags from gofmt: no need to change default
- removed option to reverse declaration order when printing
- excluded files from test that cause trouble with idempotency test for now

8c253bcae5 first attempt at real FFI support. 
in a .6 file, an export line

	//ffi T localfib remotefib remote.so

means the dynamic linker should initialize
localfib, always a pointer, to the address of
remotefib, either text (T) or data (D) after
loading remote.so.

the C compiler will generate an export section
when given the pragmas

	#pragma package fib
	#pragma ffi T localfib remotefib remote.so

needing #pragma package is a bit of a kludge
and hopefully could go away later.

this is just the 6 tool chain support.
other architectures will happen once 6 settles down.

code using this to do FFI is in a later CL.

bd4161fcba FFI step 2: can ask for libc.so.6. 
introduced explicit "data" symbol instead of etext
to mark beginning of data, so that using larger
alignment (i.e. 4MB like GNU loader) doesn't
confuse garbage collector.

split dodata into dodata and dobss in preparation
for putting the dynamic data + headers in the data
segment instead of stuffed at the beginning of the binary.
