Adrià FranchandClaude f3b74e2cef fix(shader): choose unary f32/f16 special results on the bits, as RDNA does ...

v_ceil/floor/trunc/rndne/fract/sqrt/rsq/rcp/rcp_iflag/log/exp/sin/cos
(f32 and f16) and v_frexp_mant_f32 left NaN, invalid, zero and infinite
results to the driver: signalling NaNs came back unquieted, lavapipe lost
the NaN sign and payload, invalid results were +NaN instead of -NaN, f32
sin/cos at whole and half cycles returned tiny values instead of +0, and
v_fract_f16 of a tiny negative rounded up to 1.0.

Adds an execution test for the 27 opcodes with expected values from
hardware; approximate ops are compared with tolerances from the Vulkan
precision table.
