dcd4579226 Handle a function returning bool, char or short
x86-64 psABI says that only the least significant 8 bits are
significant if RAX has a return value of a function returning bool.
Likewise, it looks like only the least significant 1 or 2 bytes
are guaranteed to have a correct value for char and short return
values, respectively.

5b95533603 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}`.
