0ad1239522 rework enums and unions and their relationship to each other 
* @enumTagName renamed to @tagName and it works on enums and
   union-enums
 * Remove the EnumTag type. Now there is only enum and union,
   and the tag type of a union is always an enum.
 * unions support specifying the tag enum type, and they support
   inferring an enum tag type.
 * Enums no longer support field types but they do support
   setting the tag values. Likewise union-enums when inferring
   an enum tag type support setting the tag values.
 * It is now an error for enums and unions to have 0 fields.
 * switch statements support union-enums

4543413491 std.io: introduce buffered I/O and change API 
I started working on #465 and made some corresponding std.io
API changes.

New structs:
 * std.io.FileInStream
 * std.io.FileOutStream
 * std.io.BufferedOutStream
 * std.io.BufferedInStream

Removed:
 * std.io.File.in_stream
 * std.io.File.out_stream

Now instead of &file.out_stream or &file.in_stream to get access to
the stream API for a file, you get it like this:

var file_in_stream = io.FileInStream.init(&file);
const in_stream = &file_in_stream.stream;

var file_out_stream = io.FileOutStream.init(&file);
const out_stream = &file_out_stream.stream;

This is evidence that we might not need any OOP features -
See #130.

634e8713c3 add @memberType and @memberName builtin functions 
see #383

there is a plan to unify most of the reflection into 2
builtin functions, as outlined in the above issue,
but this gives us needed features for now, and we can
iterate on the design in future commits

9e234d4208 breaking change to std.io API 
* Merge io.InStream and io.OutStream into io.File
 * Introduce io.OutStream and io.InStream interfaces
   - io.File implements both of these
 * Move mem.IncrementingAllocator to heap.IncrementingAllocator

Instead of:

```
%return std.io.stderr.printf("hello\n");
```

now do:

```
std.debug.warn("hello\n");
```

To print to stdout, see `io.getStdOut()`.

 * Rename std.ArrayList.resizeDown to std.ArrayList.shrink.

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

d7a539906d Merge branch 'embed-lld' 
Zig now depends on LLVM 5.0.0.

For the latest version that supports LLVM 4.0.1, use
2a49c876be.

Unfortunately we had to embed LLD into Zig due to some
MACH-O related LLD bugs. One of them is already upstream
and another is awaiting feedback on the llvm-dev mailing
list.

You can use cmake option -DZIG_FORCE_EXTERNAL_LLD=ON to
still use external LLD if you want to live with the MACH-O
bugs or if your system LLD is patched.

Closes #273
