Henrik RydgårdandClaude Fable 5.1 2d14cad065 FPU: sqrt.s of a negative gives the PSP's positive NaN ...

x86 (SQRTSS and libm alike) returns 0xffc00000 for it, the PSP 0x7fc00000.
-0 stays -0 and a NaN input comes through as it is, so only a negative
input needs the sign cleared: a compare and an xor in the x64 JITs, a
branch in the interpreters. cpu/fpu/roundmode.
