Transactional Synchronization Extensions are supported on certain Intel's
CPUs only, hence can be put under CONFIG_INTEL build option.
The whole TSX support, even if supported by CPU, may need to be disabled via
options, by microcode or through spec-ctrl, depending on a set of specific
conditions. To make sure nothing gets accidentally runtime-broken all
modifications of global TSX configuration variables is secured by #ifdef's,
while variables themselves redefined to 0, so that ones can't mistakenly be
written to.
