Joseph Myers ff57bb7b63 target/i386: reimplement fpatan using floatx80 operations
The x87 fpatan emulation is currently based around conversion to
double.  This is inherently unsuitable for a good emulation of any
floatx80 operation.  Reimplement using the soft-float operations, as
for other such instructions.
