This patch is the result of running run-clang-tidy -fix -header-filter=.* -checks='-*,modernize-use-equals-default' . Code style changes have been done on top. The result of this change leads to the following improvements: 1. Binary size reduction. * For a -DBUILD_CONFIG=mysql_release build, the binary size is reduced by ~400kb. * A raw -DCMAKE_BUILD_TYPE=Release reduces the binary size by ~1.4kb. 2. Compiler can better understand the intent of the code, thus it leads to more optimization possibilities. Additionally it enabled detecting unused variables that had an empty default constructor but not marked so explicitly. Particular change required following this patch in sql/opt_range.cc result_keys, an unused template class Bitmap now correctly issues unused variable warnings. Setting Bitmap template class constructor to default allows the compiler to identify that there are no side-effects when instantiating the class. Previously the compiler could not issue the warning as it assumed Bitmap class (being a template) would not be performing a NO-OP for its default constructor. This prevented the "unused variable warning".
