Added g_branch() to cc65's code generator.
...
It uses BRA if the platform's CPU has BRA. Else, it generates a JMP.
(Used it in the bitfield sign-extending code.)

Treat signed int bit-fields as signed
...
Prior to this PR, `int`, `signed int`, and `unsigned int`
bitfields are all treated as `unsigned int`.
With this PR, `signed int` will be treated as `signed int`,
and the others remain unsigned.
Since `Type` does not distinguish between `int` and `signed int`,
add an extra `int* SignenessSpecified` param to `ParseTypeSpec`
so we can tell these apart for bit-fields and treat plain `int : N`
as `unsigned int : N` since it is more efficient to zero-extend
than sign-extend.
Fixes #1095

Changed the type of a compiler variable that holds either integers or pointers.
...
The change allows cc65 to be compiled on 64-bit Windows, without getting warnings. That OS is actually 32 bits with 64-bit pointers. Its pointers are "long long" instead of "long". The change uses type-names that are configured for the actual pointer width.

* Added several type casts to increase C++ compatibility.
...
* __fixargs__ is now an actual function symbol and no longer handled in the
scanner.
* Additional symbol __argsize__ that is a constant in normal functions and
a const local variable for variadic functions. Using this symbol, the
va_arg macro gets a lot simpler and smaller.
* Added special code to handle the fixed parameters of a variadic function.
The code has some overhead, but the va_fix macro is no longer needed (and
the compiler generated code is better than va_fix anyway).
