x86 (__HAVE_FLOAT128): Defined to 0 for Intel SYCL compiler [BZ #32723]

Browse Source 
Intel compiler always defines __INTEL_LLVM_COMPILER.  When SYCL is
enabled by -fsycl, it also defines SYCL_LANGUAGE_VERSION.  Since Intel
SYCL compiler doesn't support _Float128:

https://github.com/intel/llvm/issues/16903

define __HAVE_FLOAT128 to 0 for Intel SYCL compiler.

This fixes BZ #32723.
