9e2f2fcd2e compilers were inconsistent about
whether no register argument was
REGARG == 0 or REGARG < 0.
use REGARG < 0 because arm needs 0 for R0.

0dadc4fe4f cleanup in preparation for new scoping.
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).

  are *ast.CommentGroups
- clarified distinction between leading and trailing comments
- fixed a bug in comment collection (parseGenDecl);
  corresponding test case is in printer/testdata
- extra documentation

doc.go:
- collect BUG comments

903d28bd1e ANY is already checked separately,
so remove code from go.y.

show original types in badtype; don't remove pointers.
not sure why this was here but it confuses things
if the bad part involves two named pointer types
with different names but the same pointed-at type.

88e7fd5410 in preparation for changing 6g's behavior to
align the output args separately from the input args,
change cgo2c to insert the necessary padding
when the two arg lists are concatenated in the c
translation.

for example, there is a runtime

	func indexstring(s string, i int32) (b byte)

right now in 6g those arguments are aligned in one
struct with s at offset 0, i at 16, and b at 20.
soon the b byte will be in its own struct and structs
are 8 aligned, so it will be b at 24.

right now cgo2c generates:

	void indexstring(string s, int32 i, byte b)

this CL makes it generate, in --6g mode:

	void indexstring(string s, int32 i, uint32, byte b)

this is valid 6c input, although not valid gcc input.
(the code is being generated for 6c only anyway.)

also, allow C code to be mixed in among the Go funcs.
every instance of the token `func' is expected to start
a new go func.
