Hello,
This patch introduces switches necessary for new Intel Server CPU
(code-named Skylake).

Bootstrapped & regtested.

Is it ok for trunk?

gcc/
	* config.gcc: Support "skx".
        * config/i386/i386-c.c (ix86_target_macros_internal): Handle
        PROCESSOR_SKX.
        * config/i386/i386.c (m_SKX): Define.
        (processor_target_table): Add "skx".
        (PTA_SKX): Define.
	(ix86_option_override_internal): Add "skx".
        (fold_builtin_cpu): Handle "skx".
        * config/i386/i386.h (TARGET_SKX): Define.
        (processor_type): Add PROCESSOR_SKX.
        * config/i386/i386.md (attr "cpu"): Add knl.
        * config/i386/x86-tune.def: Add m_KNL.

gcc/testsuite/
        * gcc.target/i386/funcspec-5.c: Test avx512vl, avx512bw,
	avx512dq, avx512cd, avx512er, avx512pf and skx.
