Integer literals

[Charles]

Cobra now handles int literals outside the signed 32-bit range with having to specify a suffix (eg, 0xffffffff_u32) as seen here:

class A

    def foo
        a = 0xfffffff
        assert a.typeOf is int32
        b = 0xffffffff
        assert b.typeOf is uint32
        c = 0xfffffffff
        assert c.typeOf is int64
        d = 0xffffffffffffffff
        assert d.typeOf is uint64

    def bar
        a = 268_435_455
        assert a.typeOf is int32
        b = 4_294_967_295
        assert b.typeOf is uint32
        c = 68_719_476_735
        assert c.typeOf is int64
        d = 18_446_744_073_709_551_615
        assert d.typeOf is uint64

The type inference is taken straight from C#. The type of the int literal is the first in this list whose range can contain the literal:

int, uint, int64, uint64

You can still use the suffixes (suffices?) if you like; they're not going away. They can also still be useful for smaller values like 0xFF_u8.
