Fix OpenCL-CTS error in `math_brute_force/test_bruteforce -w ldexp` Valhall LDEXP.v2f16 takes a 16-bit exponent, while NIR ldexp uses a 32-bit exponent. Truncating large exponents can flip overflow into underflow or leave huge 16-bit exponents to hardware behavior that does not match OpenCL's expected signed infinity/zero results. Clamp the exponent to a range sufficient to overflow or underflow all fp16 values before lowering to ldexp16_pan.
