.ds directive breaks .adr operator

[phaeron1024]

Labels declared with separate load and run addresses via the ORG directive no longer have the correct aliased address after a .ds directive, breaking the .adr operator on those labels.

Repro code:

        org     $2000

        lda     r1
        lda     r2
        lda     r3
        lda     .adr r1
        lda     .adr r2
        lda     .adr r3

        org     0,$4000
r1:
        nop
r2:
        .ds     1
r3:

After the .ds directive, r3 and .adr r3 have the same address. This is apparently because .ds resets both ORG addresses to be the same instead of maintaining the offset.

after changing the assembly address of the .PROC, .LOCAL block, it is not possible to use the .DS directive
