[PATCH 73/76] target/i386: Detect flush-to-zero after rounding

The Intel SDM section 10.2.3.3 on the MXCSR.FTZ bit says that we flush outputs to zero when we detect underflow, which is after rounding. Set the detect_ftz flag accordingly. This allows us to enable the test in fma.c which checks this behaviour. Signed-off-by: Peter Maydell --- target/i386/tc
