    i386: Fix up some FMA patterns for -masm=intel [PR124315]

    The following 4 define_insns don't have matching operands between AT&T and
    Intel syntax, %3 is "0" and %1 was missing.
    Searched grep '%0%{%4%}|%0%{%4%}' *.md and didn't find other spots where
    the operand numbers wouldn't match (reverse order of course).
