  libclc: frexp: fix implementation regarding denormals (#134823)

Devices not supporting denormals can compare them true against zero. It
leads to result not matching the CTS expectation when either supporting
or not denormals.

For example for 0x1.008p-140 we get {0x1.008p-140, 0} while the CTS
expects {0x1.008p-1, -139} when supporting denormals, or {0, 0} when not
supporting denormals (flushed to zero).
