Subject: [PATCH] Remove register keyword which is deprecated in C++17

This fixes warnings with clang like this
warning: 'register' storage class specifier is deprecated and incompatible with C++17 [-Wdeprecated-register]

According to https://en.cppreference.com/w/cpp/keyword/register
the keyword is unused and reserved.
