Intel didn't port gcc to x86's, although some time ago Intel optimized
the existing x86 gcc port.  I tried their optimized version and found
it so buggy as to be unusable.  Apparently Intel made their changes in
the Wrong way (e.g. made platform-specific changes to the
platform-independent portions of gcc), and the gcc maintainers were
unable to use Intel's work.  Richard Kenner (who seems to be gcc's
primary maintainer these days) posted a fairly long and detailed list
of reasons he couldn't use Intel's "improvements".

I've heard Cygnus plans to devote a lot of effort to improving gcc for
the x86, though.
