dc7b2e98d2 compiler changes for *chan -> chan; *map -> map; new(T) -> new(*T) 
mainly a syntactic change: the compiler representations don't change
(chan and map are now hidden pointers like string).

67addd4e11 symbol table changes 
* add gotype string to symbol table
	* fill in gotype in 6l for known funcs/vars
	* print gotype with nm -t

	* load symbol and pc/ln tables into memory at magic address 0x99<<32.
	* add sys.symdat() to retrieve raw bytes of symbol table
	  and pc/ln table.

most of this should be considered experimental
and subject to change.
