IBM zSystems: Accept (. - 0x100000000) PCRel32 operands
as does not accept instructions like brasl %r0,.-0x100000000, because
of two problems with the generic overflow check:
1. PCRel32 operands are signed, but are treated as unsigned.
2. The allowed range for these operands is [-(1 << 32), (1 << 32) - 1],
and not [-(1 << 31), (1 << 31) - 1].
Fix both by disabling the generic overflow check - it's not needed,
because s390_insert_operand () performs its own.
