Henrik RydgårdandClaude Fable 5.1 fc9dbf5ff5 FPU: saturate float-to-int in the interpreters ...

The C cast is undefined past the int32 range, and x86 makes it INT_MIN, so
round/trunc/ceil/floor/cvt.w.s of anything from 2^31 up gave 0x80000000 on
x86 hosts while the PSP saturates to 0x7fffffff (cpu/fpu/roundmode). Route
all of them through SaturatedFloatToInt, which also covers NaN and inf, and
drop the special cases that did.
