Adhemerval Zanella 721314c980 x86_64: Remove avx512 strstr implementation 
As indicated in a recent thread, this it is a simple brute-force
algorithm that checks the whole needle at a matching character pair
(and does so 1 byte at a time after the first 64 bytes of a needle).
Also it never skips ahead and thus can match at every haystack
position after trying to match all of the needle, which generic
implementation avoids.

As indicated by Wilco, a 4x larger needle and 16x larger haystack gives
a clear 65x slowdown both basic_strstr and __strstr_avx512:

  "ifuncs": ["basic_strstr", "twoway_strstr", "__strstr_avx512",
"__strstr_sse2_unaligned", "__strstr_generic"],

    {
     "len_haystack": 65536,
     "len_needle": 1024,
     "align_haystack": 0,
     "align_needle": 0,
     "fail": 1,
     "desc": "Difficult bruteforce needle",
     "timings": [4.0948e+07, 15094.5, 3.20818e+07, 108558, 10839.2]
    },
    {
     "len_haystack": 1048576,
     "len_needle": 4096,
     "align_haystack": 0,
     "align_needle": 0,
     "fail": 1,
     "desc": "Difficult bruteforce needle",
     "timings": [2.69767e+09, 100797, 2.08535e+09, 495706, 82666.9]
    }

PS: I don't have an AVX512 capable machine to verify this issues, but
    skimming through the code it does seems to follow what Wilco has
    described.
