Joseph Myers ddb2f1d4dd target/i386: reimplement fyl2x using floatx80 operations ... The x87 fyl2x 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, building on top of the reimplementation of fyl2xp1 and factoring out code to be shared between the two instructions. The included test assumes that the result in round-to-nearest mode should always be one of the two closest floating-point numbers to the mathematically exact result (including that it should be exact, in the exact cases which cover more cases than for fyl2xp1).
