Log Message:
-----------
Fix offset calculations in EmitterAARCH64 (#2022)
'varOffset' is defined as
Address varOffset = addr - gen.currAddr() + 4;
When 'addr' is less than 'gen.currAddr()', this calculation underflows.
Since 'labs' takes a 'long int', the underflowed 'unsigned long' (that
is what 'Address' really is) gets converted to a signed value. Removing
this conversion and the subsequent absolute value caused 'varOffset' to
be treated as a large, positive number.
This was broken by 9b6dd2aa6b.
