By the way, the "test_0_sqrt_precision_and_spill" test still
fails, but this is not exactly related to this bug... I am
still investigating it.

+fldz-fadd is safe, since we never allocate all the slots in the fp
+stack. If it was an issue it's likely much better to use a fadd with a
+memory reference to a 0.0 value instead of building it on the stack,
+which is slow and requires more code.
+There is no need to split the add of 0: it buys us nothing that I can
+see. Please put the additional tests in a file different from
+basic-float.cs: the tests there should test very basic functionality
+that doesn't require method calls etc.
