x86: Add missing float-to-integer cast operation to CVTSD2SI/CVTSD2SI

[Sleigh-InSPECtor]

CVTSS2SI/CVTSD2SI are instructions for converting scalar floating point values to integers.

In the SLEIGH spec, the float-to-integer cast operation (trunc) is missing in the constructors for handling the case where the size destination operand matches the floating point source operand size. (My guess is that the original author assumed that the round operation performed the cast not the trunc op).

e.g.:

f30f2dc0 "CVTSS2SI EAX, XMM0" with XMM0=0x41200000 (10.0)

• Hardware Reference (AMD CPU): { RAX = 0xa }
• x86:LE:64:default (Existing): { RAX = 0x41200000 }
• x86:LE:64:default (This patch): { RAX = 0xa }
