interface = (*int)(nil) is not the same as
interface = nil.

* use structs instead of interfaces
* compiler lays out data structures ahead of time,
so no more parsing of strings.
* unified reflect data structures with interface
runtime data structures.
* richer data structures should enable reflection
on chans and maps, but not implemented here.

- display: show '...' if a struct/interface has fields/methods removed; show
struct/interface w/o {}'s if all fields/methods were removed; and show the
{}'s if the struct/interface was empty to begin with

- use FilterExports instead of the various predicates in printer.go and doc.go
which simplifies a lot of code and makes it easier to deal with complex cases

if there is an error, we will write one more value into the struct but in return
we do fewer tests in the decode.

now that cgo2c can handle it,
merge x.c and x_go.cgo into
a single x.cgo, for x=float,malloc,sema.

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.
