Usual unary conversions (promotions) should promote unsigned char to int, not unsigned int.
...
This fixes the compca13.c test case.

Do an explicit conversion when converting from signed to unsigned byte values. This is needed because the value is held in a 16-bit register, sign-extended. The high 8 bits need to be cleared to convert to an unsigned byte.
...
This fixes the compca06.c test case.
Note that this generates inefficient code in the case of loading a signed byte value and then immediately casting it to unsigned (it first sign-extends the value, then masks off the high bits). This should be optimized, but at least the generated code is correct now.

Disable an invalid optimization that would suppress stores of address values when they appeared to the left of the comma operator.
...
This fixes the compca22.c test case.
This optimization could be fixed and re-enabled, but to do so, you would have to check if the stored value is ever used subsequently, which is not information that's readily available in the peephole optimization pass. It would also be necessary to check if there are any stores to the same location within the right-side expression, which could kill the optimization.

Don't do common subexpression elimination for indirect accesses where there is an intervening operation that may write to the same location.
...
This fixes the bug in the compca05.c test case.
