excluding import data, no yacc node has type Type* anymore. 0 reduce/reduce conflicts. R=ken OCL=31793 CL=31795

2009-07-17another step toward eliminating forward declarations.Russ Cox1-826/+874
introduce NodeList* type in compiler to replace OLIST. this clarifies where lists can and cannot occur. list append and concatenation are now cheap. the _r rules are gone from yacc. rev and unrev are gone. no more lists of lists. the representation of assignments is a bit clunkier. split into OAS (1=1) and OAS2 (2 or more on one side). delete dead chanrecv3 code. delay construction of func types. R=ken OCL=31745 CL=31762
2009-07-13step toward no function prototypes.Russ Cox1-28/+175
delay evaluation of most types (all but func) from parse time to type check time. R=ken OCL=31585 CL=31585
2009-07-10cleanup in preparation for new scoping.Russ Cox1-388/+299
walkstate -> walkstmt walktype -> walkexpr; stmts moved to walkstmt walktype and friends have a final Node **init argument that can have side effects appended, making it more explicit when they do and do not happen. this replaces the old global addtop and addtotop. delete switch map and interface conversion cases (dropped from the language months ago).

that came from two different enums. spilt into ifacecvt and ifaceop depending on which enum the argument is. R=ken OCL=29122 CL=29122
2009-05-20change representation of interface values.Russ Cox1-16/+101
this is not a user-visible change. before, all interface values were struct Itype { Sigt *type; Sigi *inter; void *method[n]; } struct Iface { void *addr; Itype *itype; } the itype is basically a vtable, but it's unnecessary if the static type is interface{ }. for interface values with static type empty, the new representation is struct Eface { void *addr; Sigt *type; } this complicates the code somewhat, but it reduces the number of Itypes that have to be computed and cached, it opens up opportunities to avoid function calls in a few common cases, and it will make it possible to lay out interface{} values at compile time, which i think i'll need for the new reflection. R=ken OCL=28701 CL=29121
