get rid of panic for typedef void (interprets as typedef int8_t)

[g41797]

For discussion only

[g41797]

C: typedef _int8t IOTEST_t; IOTEST_t *test;

go: type IOTEST_t int8 var test *IOTEST_t

C: typedef void IOTEST_t; var test *IOTEST_t

go: type IOTEST_t int8 var test unsafe.Pointer

After discussion I'll revert this PR

As discussed in PM, it should probably use struct{} instead of int8.

[g41797]

for int8_t i added following code: if isTypedef && vt == nil { vt = types.IntT(1) }

the same code for struct uses StructT(nil)

for C code typedef void IOTEST_t;

void main() { IOTEST_t *test; }

created go code: import "unsafe"

type IOTEST_t struct { }

func main() { var test unsafe.Pointer _ = test }

is it enough?

btw func (t *StructType) Sizeof() int { should return 1 for fieldless struct is it OK?
