e0c12c90cd g_asr, g_asl: Use ROL/ROR for char shifts by >= 6 
Instead of `val` right (left) shifts, we can also do `9 - val` left (right)
rotates and a mask.  This saves 3 bytes and 8 cycles for `val == 7` and
1 byte and 4 cycles for `val == 6`.

dfd047ce6a g_typeadjust: Use CF_CHAR for char args 
If lhs and rhs are either both signed char or both unsigned char,
return flags for that type instead of (unsigned) int.  The flags
are used only for codegen.  Currently, this does nothing, since
codegen treats chars as ints unless CF_FORCECHAR is set, but it
allows more efficient char x char -> int codegen to be added in
the future.

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.

2646c06f61 docs: fix simple typo, paramater -> parameter 
There is a small typo in src/cc65/pragma.c.

Should read `parameter` rather than `paramater`.

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.

cffcbce60f Bumped version. 
I placed the Git tag V2.19 in hindsight at 555282497c. But I certainly don't want to rewrite the Git history just for the reported version, so I simply set the reported version at today's HEAD to 2.19.
