68796b0270 gc: add ... T, rework plain ...
No longer a distinct type; now a property of func types.

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.

24bfaaf07a - added gcmp for proper ACMP generation, changed all call
sites plus optimized constant code a bit (one less register
  used).
- changed conditional branches, might need a re-tweak later

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

eac5db7f4c Copied 8g/6g into 5g. Used sharp tools to coax a .5 file out
of 5g. 5l balks at the output and running 5g with -S shows
the true extent of the disaster. Still, better than
yesterday. Maybe.

Tested on the canonical:

package main
func main() {
}
