8433503792 Make sure that undefined global symbols don't get reduced to 0 when negated 
Test case:

        ; test complex relocations

        ; .globl  IE.ITS,IE.MON ; implicit
        mov     #-IE.ITS, space

space:  .word   IE.ITS    ; the only simple relocation
        .word   -IE.ITS   ; all others are complex relocations
        .word   ^C<IE.ITS>
        .word   IE.ITS + IE.MON
        .word   IE.ITS - IE.MON
        .word   IE.ITS * IE.MON
        .word   IE.ITS / IE.MON
        .word   IE.ITS & IE.MON
        .word   IE.ITS ! IE.MON

cf320a2e60 Fix use-after-free errors. 
evaluate() would not-quite-copy the original tree, which often would
get freed afterward. Including the shared parts.
Also fixed the case where evaluate() would turn a EX_NEG node into an
EX_COM node.
