Constant data size regression

[Andrew Stubbs]

The following code demonstrates a significant data size regression. With 4.3 based toochains it requires only 8 bytes of rom. With 4.4. based toolchains and above, each array is aligned to a 4-byte boundary. My application has several hundred such off sized arrays, so no longer fits in rom.

Adding __attribute__((aligned(1))) works around the problem, however the additional alignment seems rather suspect at -Os.

const char data1[] =
{
  1, 2, 3, 4, 5
};

const char data2[] =
{
  7, 8, 9
};

I see this is already merged into Linaro 4.5, closing.
