c413c45e6d cmd/internal/obj: make Prog.From3 a pointer 
It is almost never set and Addr is large, so having the full struct
in the Prog wastes memory most of the time.

Before (on a 64-bit system):

$ sizeof -p cmd/internal/obj Addr Prog
Addr 80
Prog 376
$

After:

$ sizeof -p cmd/internal/obj Addr Prog
Addr 80
Prog 304
$

17eba6e6b7 cmd/compile, cmd/link: create from 5g, 5l, etc 
Trivial merging of 5g, 6g, ... into go tool compile,
and similarlly 5l, 6l, ... into go tool link.
The files compile/main.go and link/main.go are new.
Everything else in those directories is a move followed by
change of imports and package name.

This CL breaks the build. Manual fixups are in the next CL.

See golang-dev thread titled "go tool compile, etc" for background.
