Extended Description

The output from the SystemZ backend gives fatal errors when trying to assemble with the GNU binutils 2.20.51.20100224 assembler for s390x. This happens when assembling the output of the distributed test cases for SystemZ.

A minimal test case is attached. I'll attach the -debug output from llc next.

$ llc -march=systemz RetImm16LL.ll
$ s390x-as -m64 -march=z900 RetImm16LL.s
RetImm16LL.s: Assembler messages:
RetImm16LL.s:8: Error: operand out of range (0xffffffffffffffff is not between 0x0000000000000000 and 0x000000000000ffff)

In RetImm16LL.s
the line
llill %r2, -1
should be
llill %r2, 65535

Looks good to me. Committed as r124679. Thanks!
