[PATCH, i386]: __builtin_cpu_is() is not detecting bdver2 with Model = 0x02

[Uros Bizjak]

Hello!

As reported in the PR, AMDFAM15H model 0x2 should return
AMDFAM15H_BDVER2 subtype.

    * config/i386/cpuinfo.c (get_amd_cpu): Return
    AMDFAM15H_BDVER2 for AMDFAM15H model 0x2.

Bootstrapped and regression tested on x86_64-linux-gnu {,-m32}.

Committed to mainline SVN.
