816689a3b1 ptrCast gives compile error for increasing alignment 
See #37

c5c9d98065 introduce align keyword 
* remove `@setGlobalAlign`
 * add align keyword for setting alignment on functions and
   variables.
 * loads and stores use alignment from pointer
 * memcpy, memset use alignment from pointer
 * add syntax for pointer alignment
 * slices can have volatile
 * add u2, i2 primitives
 * ignore preferred align and use abi align everywhere
 * back to only having alignOf builtin.
   preferredAlignOf is too tricky to be useful.
   See #432. Partial revert of
   e726925e80.

e5b90651ba compileError builtin includes "referenced by" notes

2dfb1ebee2 const global values can reference each other 
Before, if you did something like:

```
const hi1 = "hi";
const hi2 = hi1;
```

This would create the "hi" data twice in the built object.
But since the value is const we don't have to duplicate the
data, now we take advantage of this fact.

a32b5929cc add stack protector safety when linking libc 
* introduce zigrt file. it contains only weak symbols so that
   multiple instances can be merged. it contains __zig_panic
   so that multiple .o files can call the same panic function.
 * remove `@setFnVisible` builtin and add @setGlobalLinkage builtin
   which is more powerful
 * add `@panic` builtin function.
 * fix collision of symbols with extern prototypes and internal
   function names
 * add stack protector safety when linking against libc. To add
   the safety mechanism without libc requires implementing
   Thread Local Storage. See #276

* Rip out legacy code for generics
 * put scope in instruction instead of AST nodes
 * separate top level decl stuff from AST nodes

     between an output instruction and an AST node
   - This way we won't have to clone AST nodes for generics.

* Introduce the concept of packages. Closes #3
 * Add support for error notes.
 * Introduce `@import` and `@c_import` builtin functions and
   remove the `import` and `c_import` top level declarations.
 * Introduce the `use` top level declaration.
 * Add `--check-unused` parameter to perform semantic
   analysis and codegen on all top level declarations, not
   just exported ones and ones referenced by exported ones.
 * Delete the root export node and add `--library` argument.
