Spurious itemized line in Parameter passing

[jakubjelinek]

When reading Parameter passing chapter, I'm seeing weird:
• The 64-bit mantissa of arguments of type long double
• The 64-bit mantissa of arguments of type long double belongs to class
X87, the 16-bit exponent plus 6 bytes of padding belongs to class X87UP.
The second item describes what happens, but the first item looks like some left-over.

x86-psABI/low-level-sys-info.tex

Line 425 in 8531508

\item The 64-bit mantissa of arguments of type \code{long double}

should be IMHO deleted.

Agree. It should be removed.
