The indefinite integer value for CVTSS2SI in SDM Volume 2

[aratamizuki]

The description of CVTSS2SI (and other floating-point→signed int conversions) describes the indefinite integer value as 2^w-1, but the correct value seems to be -2^(w-1).

Screenshot from Vol. 2A 3-301 says 2^w-1 (seems wrong):

Screenshot from Vol. 1 D-7 says 80000000H or 8000*00 (seems correct):

These screenshots are from SDM June 2024 version.
