test/codegen: fix a tab in comparisons.go to ensure pattern works
Fix a pattern in test/codegen/comparisons.go to use whitespace instead
of a tab. The test needs a whitespace to properly fail if the regalloc
change from CL686655 would be missing (in that case we would have a
spill immediately after call to memequal, which is supposed to be
captured by this pattern).
