325ff9667e Used (size_t), instead of (long) where converting between pointers and integers. 
(long) still is 32 bits on 64-bit Windows!

e5813cfb1a Removed two duplicate TYPEDEFs from a header. 
The first one is replaced by an #include of the header that has its original TYPEDEF.
The second one is replaced by its base type.

Details:
  The push and pop facilities are implemented directly inside the tgttrans.h,
  to facilitate its reuse on the C compiler.

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.

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.

060417b0dc Adjust type of int constants that fit in char 
When there is an integral constant like `3` in an expression, it has
type `int` according to the C spec, even though it can be represented
as an `unsigned char`.  Change codegen (`hie_internal` and `typeadjust`)
to treat it as `unsigned char` instead of `int` so that faster,
unsigned operations can be used.

For the test case in #1298, reduces the cycles per iteration from
4311 to 1884.  This is a great improvement, but still much worse than
the 1053 cycles/iter from `c4698df~`, so more work remains to be done.

Further partial fix for #1298 and #1308.

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.
