793f031c4c remove 32-bit windows from supported targets list 
we still want to support it, but there are too many bugs
to claim that we support it right now.

bb39e503c0 fix struct inside function referencing local const 
closes #672

the crash and compile errors are fixed but structs
inside functions still get named after the functions
they're in. this will be fixed later.

0ea50b3157 ir: new pass iteration strategy 
Before:
 * IR basic blocks are in arbitrary order
 * when doing an IR pass, when a block is encountered, code
   must look at all the instructions in the old basic block,
   determine what blocks are referenced, and queue up those
   old basic blocks first.
 * This had a bug (See #667)

Now:
 * IR basic blocks are required to be in an order that guarantees
   they will be referenced by a branch, before any instructions
   within are referenced.
   ir pass1 is updated to meet this constraint.
 * When doing an IR pass, we iterate over old basic blocks
   in the order they appear. Blocks which have not been
   referenced are discarded.
 * After the pass is complete, we must iterate again to look
   for old basic blocks which now point to incomplete new
   basic blocks, due to comptime code generation.
 * This last part can probably be optimized - most of the time
   we don't need to iterate over the basic block again.

2a25398c86 fix segfault when passing union enum with sub byte... 
...field to const slice parameter

we use a packed struct internally to represent a const array

returning from blocks.

62c25af802 add higher level arg-parsing API + misc. changes 
* add @noInlineCall - see #640
   This fixes a crash in --release-safe and --release-fast modes
   where the optimizer inlines everything into _start and
   clobbers the command line argument data.
   If we were able to verify that the user's code never reads
   command line args, we could leave off this "no inline"
   attribute.
 * add i29 and u29 primitive types. u29 is the type of alignment,
   so it makes sense to be a primitive.
   probably in the future we'll make any `i` or `u` followed by
   digits into a primitive.
 * add `aligned` functions to Allocator interface
 * add `os.argsAlloc` and `os.argsFree` so that you can get
   a `[]const []u8`, do whatever arg parsing you want, and then free
   it. For now this uses the other API under the hood, but it could
   be reimplemented to do a single allocation.
 * add tests to make sure command line argument parsing works.

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.

 * Introduce io.OutStream and io.InStream interfaces

 * 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.

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.

09bd4a9a86 compile-time f32, f64 operations are now correctly lossy 
previously we used the bigfloat abstraction to do all
compile-time float math. but runtime code and comptime code
are supposed to get the same result. so now if you add a
f32 to a f32 at compile time it does it with f32 math
instead of the bigfloat. float literals still get the
bigfloat math.
