cb8fbf4772 Removed the non-existing-in-C "struct/union scope" for structs/unions.
Fixed handling of struct/union field declarations without identifiers, which do nothing.

b2c1a77bb3 Fixed the cc65 code that optimizes 16-bit compares when the high bytes are known to be equal.
Only the low bytes are compared.  Originally, signed 16-bit compares were optimized into signed 8-bit compares.  But, the sign bits are in the high bytes; and, they're equal.  Therefore, the low bytes always must be compared as unsigned numbers.
Fixes #1348.

8b42f570e9 Fixed code that caused a seg-fault after parsing a (deferred) post-count argument followed by a (nested) function-call argument.
The old broken code defers the count until the end of the (parent function's) argument list.  But, a nested function call clears the pointer to the deferred type.  That leads to an access violation.
The new code defers only until the end of each argument.  Fixes #1320.

93145246fd Add tests for u8 op s16_const
Test expressions like `unsigned char x = ...; ... = x / 2;`
These use `int` constants with values representable by
`unsigned int` / `unsigned char`, so using unsigned codegen should
be possible.

Additional tests for #1308.  These are things we want to generate better
code for, so add tests that the behavior doesn't change.

5db74b4b19 Use u16 codegen for u8 x u8 ops
In g_typeadjust, before we apply the integral promotions, we check if
both types are unsigned char.  If so, we promote to unsigned int, rather
than int, which would be chosen by the standard rules.  This is only a
performance optimization and does not affect correctness, as the flags
returned by g_typeadjust are only used for code generation, and not to
determine types of other expressions containing this one.  All unsigned
char bit-patterns are valid as both int and unsigned int and represent
the same value, so either signed or unsigned int operations can be used.
This special case part is not duplicated by ArithmeticConvert.

Partial fix for #1308.

a686988d0e Add test cases for integral promotion of chars
Both signed and unsigned chars are promoted to int by C's evaluation
rules.  It is more efficient to use unsigned operations when possible,
however.  These tests will help test the correctness of optimizations
doing that.  See #1308.

81550ca1ee CS_MergeLabels: Keep labels referenced by data
Partial fix for ICE in #1211.  This may fix enough to allow #1049 to be
fixed.

When merging labels, keep the first label with a ref that has no JumpTo;
this is a data segment label, used by computed gotos.

The real fix is to track and rewrite labels in data, but this is more
involved.

b931e65811 Fix ICE for bit-fields with typedef
Fixes #1267

Avoid ICE, but treat plain int bit-fields declared via typedef as
signed rather than unsigned.  It is more efficient to treat them
as unsigned, but this requires distinguishing int from signed int,
and this is curently not done.

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.

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.

cl65 creates intermediate files based on the source file name in the source file directory. Calling cl65 in parallel with the same source file causes those intermediate files to get overwritten.

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.
