Innodb, Windows : Reenable compiler optimizations for mem0mem.cc

Browse source 
Compiler optimizations were switched off due to
MySQL Bug #19424, #36366, #34297, due to an alleged compiler bug.
No  proper analysis of code generation was done back then, thus proof of
a compiler bug is missing.

Even if there was a compiler bug 13 years ago, it could have been fixed.
Will wait and see if there are any complains or crashes
