bf1ef6157c build: properly quote strings passed as cpp macros 
until now, the strings intended to be hardcoded into the binary,
such as directory names and build id, were passed unquoted, which
means they're interpreted by the preprocessor as C tokens, rather
than strings, which can result in all sorts of "interesting"
behaviour such as interpreting paths starting with // as C++-style
comment.
this was then worked around using a stringize macro which turned
the tokens into a string (if they happened to be in a compatible
format).

f36b9b544d Fix segfault on 64-bit LLP64 Windows builds 
There are many occurrences of unsigned long in codegen.h's function
arguments. Changing g_getimmed and g_defdata makes `make` succeed
without segfaulting. I don't know if it makes cc65 behave correctly in
all cases, or if there are more unsigned long that need to be changed.

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.

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.

81550ca1ee CS_MergeLabels: Keep labels referenced by data 
Partial fix for ICE in #1211.  This may fix enough to allow #1049 to be

this is a data segment label, used by computed gotos.

involved.
