2915464667 Fixed cc65's generation of char-type bit-shift code. 
Fixed CHAR-to-INT type conversions in the right-shift code generator.  Also fixed some printf-style format specifiers.

5f65252fa6 Added the cputdirect entry point to the cputc() functions in the two Oric libraries. 
It now is available in all libraries that have cputc().

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.

944ebbc23c atarixl configs: make size of CHARGEN configurable 
If text mode is not used, its space can be reclaimed by setting __CHARGENSIZE__
to 0.

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.

f723147f04 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.

2fcd8b934a 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.

5c43d1e04f 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.
