x86/Intel: issue diagnostics for redundant segment override prefixes

While we shouldn't outright reject such (as was wrongly done by commit
4d36230d59 ("x86: Update segment register check in Intel syntax"), as
MASM accepts them even silently, issue (by default) a warning for such
questionable constructs.
