gcc/ChangeLog:
* config/i386/x86-tune.def (X86_TUNE_FUSE_ALU_AND_BRANCH_MEM): Enable
for m_ZNVER6.
(X86_TUNE_FUSE_ALU_AND_BRANCH_MEM_IMM): Likewise.
(X86_TUNE_SSE_REDUCTION_PREFER_PSHUF): Likewise.

Hi Maintainers,
This patch enables fusion and SSE reduction tunings for znver6.
Boostrap and make check successful on x86_64-pc-linux-gnu.
Ok for trunk??
regards,
Venkat.
