[PATCH] align_value attribute in Clang

[hfinkel at anl.gov]

One aspect perhaps worth some thought:

typedef double * aligned_double_ptr __attribute__((align_value(64)));
aligned_double_ptr x;

void foo(decltype(x + 3) y, aligned_double_ptr z) {}

Does y also carry the alignment assumption? As it stands in my current patch, the answer is no -- I think that is the desirable outcome, but I could be convinced otherwise ;)

Thanks again,
Hal
