Some compiler flags have been brought forward in the perf build but
without any explicit need, for example -ggdb3. Some warnings were
disabled but the underlying warning could be addressed. Try to reduce
the number of compiler options used in the perf build, to enable
Wextra for C++, and to disable fewer compiler warnings.

Ian Rogers (6):
  perf bpf-loader: Remove unneeded diagnostic pragma
  perf build: Don't always set -funwind-tables and -ggdb3
  perf build: Add Wextra for C++ compilation
  perf build: Disable fewer flex warnings
  perf build: Disable fewer bison warnings
  perf build: Remove -Wno-redundant-decls in 2 cases
