d7e28f991d remove CXX ABI workaround 
the actual solution is you must compile zig with the same
compiler that compiled llvm, lld, and clang.

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
   e726925e802eddab53cbfd9aacbc5eefe95c356f.

35d3444e27 more intuitive left shift and right shift operators 
Before:
 * << is left shift, not allowed to shift 1 bits out
 * <<% is left shift, allowed to shift 1 bits out
 * >> is right shift, allowed to shift 1 bits out

After:
 * << is left shift, allowed to shift 1 bits out
 * >> is right shift, allowed to shift 1 bits out
 * @shlExact is left shift, not allowed to shift 1 bits out
 * @shrExact is right shift, not allowed to shift 1 bits out

Closes #413

29defd705d back to AT&T syntax for assembly 
this reverts 5c04730534ea7933855429c5fc5dc7b22eba7bc2.

sadly the quality of the intel dialect in llvm's assembly
parser has many frustrating bugs, and generally has unfortunate
syntax.

the plan is to use AT&T for now since it at least works,
and eventually zig will have its own assembly parser for
x86 and it will be as close to NASM as possible.

7f47b0c271 run alwaysinline pass in debug mode 
before this commit, the optimized IR code that is displayed in
--verbose mode is not actually what gets emitted to an object
file.

that is now corrected, and we make sure to run the alwaysinliner
pass even in debug mode, so you can rely on "inline" keyword
inlining a function, guaranteed.

See #306

41b95cc237 parseh: correct debug for forward decls 
also C typedefs emit simply `const Foo = Bar;`
since in C you can implicitly cast from a typedef
child to parent but in zig you can't.
