      [wasm] always allocate memory when guard regions are needed · d31dff84
      Eric Holk authored 
      When using trap handlers, memory references do not get any checks inserted. This
means there is no check for a null memory as happens when the memory size is
0. Normally this would be correctly caught as an out of bounds access, since the
low memory addresses are not normally mapped. However, if they were mapped for
some reason, we would not catch the out of bounds access.

The fix is to ensure WebAssembly instances always have a guard region even if
the memory is size 0.

This is a rewrite of 5e76ff5a

Note that this can lead to a large amount of unnecessary address space usage,
so we share a single reservation for empty array buffers.

      [Liftoff] Fix conditional spilling · 2589ea08
      Clemens Hammacher authored 
      On float comparisons, we need a scratch byte register for the setcc
instruction, and if none is available, we spill. But this spilling code
is skipped if one of the operands is NaN. The cache state is updated
however, so following code assumes that the spill happened.
This CL fixes this by spilling before checking for NaN, such that the
spilling code is always executed.
