Tim Northover 4a58db65a5 ARM: fix part of test which actually needed an asserts build 
This should fix a buildbot failure that occurred after r179977.

Tim Northover 798697d662 ARM: Use ldrd/strd to spill 64-bit pairs when available. 
This allows common sp-offsets to be part of the instruction and is
probably faster on modern CPUs too.

Tim Northover d9d4211fe2 ARM: don't add FrameIndex offset for LDMIA (has no immediate) 
Previously, when spilling 64-bit paired registers, an LDMIA with both
a FrameIndex and an offset was produced. This kind of instruction
shouldn't exist, and the extra operand was being confused with the
predicate, causing aborts later on.

This removes the invalid 0-offset from the instruction being
produced.
