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.

f50e7b156e mostly 64 bit support.
- fixed a number of places where we tried to allocate 64bit
  regs. added honeypot in regalloc to catch these in the future.
- implemented quad copying in sgen
- cgen64.c, add, mul
- clearfat done
- D_REGREG output from 5g (linker already knew about them)
- gmove done
- optoas almost done, last bit probably not needed
- D_SHIFT support in list.c

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.

before, there was an inconsistency:

	func() {} == func() {}

2210a643b7 Intersperse comments nicely when printing an AST.
gofmt formatted source code looks pretty good already;
with a bit more fine-tuning it should be great.

printer.go:
- Implemented comment intersperse algorithm.
  The approach is a result of many trial-and-error
  experiments but at this point reasonably simple
  and open to arbitrary fine-tuning.

parser.go:
- Simplified handling of lead and line comments
  (formerly called leading and trailing comments).
- Use a comments list instead of an array (I may
  change this back - this is not obviously better
  and uses more space).

doc.go:
- Remove comments from AST nodes that have been
  'consumed' in the documentation to avoid duplicate
  printing of them. Allows for better control of
  what is printed w/o use of printing control flags
  (which are hard to use and not fine-grained enough).

Corresponding adjustments to various clients of these
files.
