In the helper routines for VCVT float-to-int conversions, add an explicit cast rather than relying on the softfloat int32 type being exactly 32 bits wide (which it is not guaranteed to be). Without this, if the softfloat type was 64 bits wide we would get zero-extension of the 32 bit value from the ARM register rather than sign-extension, since TCG i32 values are passed as uint32_t.
