[Bug 1256283] Re: go tests failing on AArch64

[Michael Hudson-Doyle]

Sorry for the spam!  Here's round one of investigation.

The peano test is a test for segmented stacks, which is not supported on
aarch64.  So perhaps the failure is unsurprising -- it's presumably
smashing the stack.

The cplx2 failure seems to indicate a pretty serious problem with
floating point.  The test outputs:

opcode x (+7.218935e-001-5.325444e-001i) (+7.218935e-001-5.325444e-001i)

Those two floating numbers are (a) comparing unequal, which is a bit
surprising and (b) supposed to be 5+0i!
