Raise the minimum required gcc version to 4.6
Various architectures fail to build properly with older versions of the
gcc compiler.
An example from Guenter Roeck in thread [1]:
>

So update the minimum required version of gcc to 4.6.

Miscellanea:
- Update Documentation/process/changes.rst
- Remove and consolidate version test blocks in compiler-gcc.h for
versions lower than 4.6
