Subject: target/i386: Add new bit definitions of MSR_IA32_ARCH_CAPABILITIES

Git-commit: 6c997b4adb300788d61d72e2b8bc67c03a584956
References: jsc#SLE-7923

The bit 6, 7 and 8 of MSR_IA32_ARCH_CAPABILITIES are recently disclosed
for some security issues. Add the definitions for them to be used by named
CPU models.
