atarixl configs: make size of CHARGEN configurable
...
If text mode is not used, its space can be reclaimed by setting __CHARGENSIZE__
to 0.
Following a suggestion from issue #1314 .

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 .

Streamlined clock rate handling.
...
* Docs say that CLK_TCK is an obsolete alias of CLOCKS_PER_SEC so there's no point in individual definitions.
* All targets determining the clock rate at runtime can use a common handling.

Made HGR segment obligatory.
...
Requiring the HGR segment makes the configs a little less flexible, but for the intended use case the HGR segment actually is necessary. And as we learned now, making the HGR segment obligatory helps users to not shoot themselves in the foot.

Changed codegen for postfix inc/dec operations by deferring them till sequence points.

This usually allows faster & smaller code.
Note that deferred operations must still be called at sequence points even if the whole expressions containing them had constant values.

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.

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.
