Allow to omit array length if an initializer is given
...
So that you can write something like `int x[] = {1, 2, 3}`
instead of `int x[3] = {1, 2, 3}`.

Add _Bool type
...
_Bool isn't just a 1-bit integer because when you convert a value
to bool, the result is 1 if the original value is non-zero. This
is contrary to the other small integral types, e.g. char, as you
can see below:
char x = 256; // x is 0
_Bool y = 256; // y is 1

Make sizeof to accept not only an expression but also a typename
...
Previously, chibicc's sizeof accepted only an expression, so you
couldn't write something like `sizeof(int)`. Now it accepts that.

of type int having value 3.

t t = 3;
