[Stable-7.2.7 24/62] target/i386: Fix exception classes for MOVNTPS/MOVNTPD.

[Michael Tokarev]

From: Ricky Zhou <ricky@rzhou.org>

Before this change, MOVNTPS and MOVNTPD were labeled as Exception Class
4 (only requiring alignment for legacy SSE instructions). This changes
them to Exception Class 1 (always requiring memory alignment), as
documented in the Intel manual.
