Michael Krumland-DunningandClaude Opus 5.5 126b7b98a0 fix(shader): translate f32 fract, floor, ceil and frexp_mant in f32 denormal modes 1 and 2 ...

All four threw "f32 denormal mode N is not implemented" whenever
FLOAT_MODE kept only one side of the f32 denormals.

On RDNA2 (gfx1036), in every f32 round mode and at IEEE 0 and 1, mode 2
gives the results of mode 0 and mode 1 those of mode 3 with a denormal
result flushed, which only v_fract_f32 of a positive denormal produces.
The translation now matches all 118 measured inputs in modes 1 and 2.
Mode 1 of the three that run host float operations on a kept denormal
needs DenormPreserve 32, as v_min_f32 does.
