x86: Do not use __builtin_isinf_sign on clang
clang does not handle pseudo normal numbers,
It fixes the regression on test-ldouble-isinf when built with clang:
Failure: isinf (pseudo_zero): Exception "Invalid operation" set
Failure: isinf (pseudo_inf): Exception "Invalid operation" set
Failure: isinf (pseudo_qnan): Exception "Invalid operation" set
Failure: isinf (pseudo_snan): Exception "Invalid operation" set
Failure: isinf (pseudo_unnormal): Exception "Invalid operation" set
Failure: isinf_downward (pseudo_zero): Exception "Invalid operation" set
Failure: isinf_downward (pseudo_inf): Exception "Invalid operation" set
Failure: isinf_downward (pseudo_qnan): Exception "Invalid operation" set
Failure: isinf_downward (pseudo_snan): Exception "Invalid operation" set
Failure: isinf_downward (pseudo_unnormal): Exception "Invalid operation" set
Failure: isinf_towardzero (pseudo_zero): Exception "Invalid operation" set
Failure: isinf_towardzero (pseudo_inf): Exception "Invalid operation" set
Failure: isinf_towardzero (pseudo_qnan): Exception "Invalid operation" set
Failure: isinf_towardzero (pseudo_snan): Exception "Invalid operation" set
Failure: isinf_towardzero (pseudo_unnormal): Exception "Invalid operation" set
Failure: isinf_upward (pseudo_zero): Exception "Invalid operation" set
Failure: isinf_upward (pseudo_inf): Exception "Invalid operation" set
Failure: isinf_upward (pseudo_qnan): Exception "Invalid operation" set
Failure: isinf_upward (pseudo_snan): Exception "Invalid operation" set
Failure: isinf_upward (pseudo_unnormal): Exception "Invalid operation" set
