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

fda0e78b23 fix line numbers, again. 
if first function in file was dead code, it was being
discarded along with the file name information for that file.
leave the functions in the master function list longer:
let xfol take the dead code out of the code list,
and let span skip the unreachable functions during output.
