Replace custom alignment enforcement with LLVM_ALIGNAS.
This isn't perfect as it still assumes sizeof(void*) == alignof(void*),
but we can fix that when compiler support gets better.
Shrinks some Stmts that happen to inherit from Stmt and have a
SourceLocation as the first member (64 bit archs only).
