Used TAY/TYA instead of PHA/PLA when extracting a bit-field.

Without optimization, it saves a few CPU cycles. With optimization, it saves more cycles and a few bytes.

Avoided an avalanche of messages from bad bit-field declarations.

Made cc65 replace a bad bit-field type with a good one, and always parse the field width.
Shortenned a parameter name to a spelling that's consistent with other function headers.

Allow char bit-fields

unsigned int are required), but most compilers support it.

are unsigned, regardless of the `--signed-chars` option.

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 .
