Disadvantages of enforcing 16-bytes stack alignment, continued:

* Code to align the stack is generated when we call a function, even when this
function isn't going to use SSE. Which is ~90% of all functions out there.

* gcc-generated SSE code will still crash if called from code compiled by older
gcc on non-gcc compiler which chose to not align stack. Note that alternative
approach (to align stack _in the function which needs it_) will not crash if
called by code generated by old or new gcc. I like it.
