Revert "Add hack to pickup C++11 alignas" 

This reverts commit 16df6e64a8. Detailed testing is revealing some fractures. The pain point seems to be C++11 is more strict about the location of the 'alignas(N)' in the statement-expression. Some compilers accept a looser grammar; while others do not.

Clang 3.3 is rejecting some of the statements with CRYPTOPP_ALIGN_DATA(N). Others may do the same, and we need to look at ICC in particular.
