7dddc3bb875e7141ab25931d0f30a1c319bc8457 target/i386: Enable fdp-excptn-only and zero-fcs-fds
- CPUID.(EAX=07H,ECX=0H):EBX[bit 6]: x87 FPU Data Pointer updated only
on x87 exceptions if 1.
- CPUID.(EAX=07H,ECX=0H):EBX[bit 13]: Deprecates FPU CS and FPU DS
values if 1. i.e., X87 FCS and FDS are always zero.
Define names for them so that they can be exposed to guest with -cpu host.
Also define the bit field MACROs so that named cpu models can add it as
well in the future.
