4e4e4c2d21 Allow char bit-fields 
These are not required to be supported (only int, signed int, and
unsigned int are required), but most compilers support it.

https://port70.net/~nsz/c/c89/c89-draft.html#3.5.2.1
https://port70.net/~nsz/c/c89/c89-draft.html#A.6.5.8

For consistency with other integral types, plain `char` bit-fields
are unsigned, regardless of the `--signed-chars` option.

Fixes #1047

9a0e4a35e1 Fix enum bit-field ICE #1244 
This previously resulted in an ICE:
cc65: Check failed: (Entry->Type->C & T_MASK_SIGN) == T_SIGN_SIGNED,
file 'cc65/symtab.c', line 874

This CHECK is in the code that deals with changing `int` bitfields to
`unsigned int`.

Work around this by treating enum bit-fields as having their signedness
specified, so this type change code does not get called.

Fixes #1244.

ff535b8e1a 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
