Signalling NaNs were being converted to quiet NaNs during constant propagation through integer <-> float store-to-load forwarding. This occurs because we store float32 constants as float64 values and CPU hardware 'quietens' NaNs during conversion between the two. Eventually we want to move to using float32 values to store float32 constants, however this will be a big change since both the compiler and the assembler expect float64 values. So for now this is a small change that will fix the immediate issue. Fixes #27193.
