Added .asize and .isize pseudo variables
...
These pseudo variables will return the size of the accumulator/index
in bits.
For the 65816 instruction set .ASIZE/.ISIZE will return either 8 or 16,
depending on the current size of the operand in immediate addressing
mode.
For all other CPU instruction sets, .ASIZE/.ISIZE will always return 8.
For example:
; Reverse Subtract with Accumulator
; A = memory - A
.macro rsb param
.if .asize = 8
eor #$ff
.else
eor #$ffff
.endif
sec
adc param
.endmacro

Adjusted current working directory initialization on Apple and Atari.
...
Moving __cwd from BSS into INITBSS does of course ;-) not only impact the CBM targets but all targets with disk I/O support.
Note: Code using `__cwd-1` may trigger an ld65 range error because __cwd may end up at the very begining of a segment. As far as I see this is an ld65 bug which I'm not try to fix - at least here.

Changed run location of INIT segment.
...
So far the INIT segment was run from the later heap+stack. Now the INIT segment is run from the later BSS. The background is that so far the INIT segment was pretty small (from $80 to $180 bytes). But upcoming changes will increase the INIT segment in certain scenarios up to ~ $1000 bytes. So programs with very limited heap+stack might just not been able to move the INIT segment to its run location. But moving the INIT segment to the later BSS allows it to occupy the later BSS+heap+stack.
In order to allow that the constructors are _NOT_ allowed anymore to access the BSS. Rather they must use the DATA segment or the new INITBSS segment. The latter isn't cleared at any point so the constructors may use it to expose values to the main program. However they must make sure to always write the values as they are not pre-initialized.
