[ValueTracking] Bail out on x86_fp80 when computing fpclass with knownbits (#130477) ...

In https://github.com/llvm/llvm-project/pull/97762, we assume the
minimum possible value of X is NaN implies X is NaN. But it doesn't hold
for x86_fp80 format. If the knownbits of X are
`?'011111111111110'????????????????????????????????????????????????????????????????`,
the minimum possible value of X is NaN/unnormal. However, it can be a
normal value.

Closes https://github.com/llvm/llvm-project/issues/130408.
