Ian Rogers 1f16fcad68 perf parse-events: Disable a subset of bison warnings
Rather than disable all warnings with -w, disable specific warnings.

Predicate enabling the warnings on a recent version of bison.

Tested with GCC 9.3.0 and clang 9.0.1.

Committer testing:

The full set of compilers, gcc and clang that this will be tested on
will be on the signed tag when this change goes upstream.

Had to add -Wno-switch-enum to build on opensuse tumbleweed:

  /tmp/build/perf/util/parse-events-bison.c: In function 'yydestruct':
  /tmp/build/perf/util/parse-events-bison.c:1200:3: error: enumeration value 'YYSYMBOL_YYEMPTY' not handled in switch [-Werror=switch-enum]
   1200 |   switch (yykind)
        |   ^~~~~~
  /tmp/build/perf/util/parse-events-bison.c:1200:3: error: enumeration value 'YYSYMBOL_YYEOF' not handled in switch [-Werror=switch-enum]

Also replace -Wno-error=implicit-function-declaration with -Wno-implicit-function-declaration.

Also needed to check just the first two levels of the bison version, as
the patch was assuming that all versions were of the form x.y.z, and
there are several cases where it is just x.y, breaking the build.
