Optimize debug builds when -Og is available
Enables optimizing with -Og if GCC has the option available, this
should produce faster debug binaries without compromising debugability.
Is a privateConfig to limit it to the default Qt build.
Includes two fixes for false positives of maybe_uninitialized triggered
by -Og on gcc 4.9.
