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

38f05d4ac5 WIN32: Linking with the CRT at runtime. (#570) 
Disclaimer: Forgive me if my format sucks, I've never submitted a PR before!

Fixes: #517 

I added a few things to allow zig to link with the CRT properly both statically and dynamically. In Visual Studio 2017, Microsoft changed how the c-runtime is factored again. With this change, they also added a COM interface to allow you to query the respective Visual Studio instance for two of them. This does that and also falls back on a registry query for 2015 support. If you're using a Visual Studio instance older than 2015, you'll have to use the existing options available with the zig compiler. Changes are listed below along with a general description of the changes.

all_types.cpp:

The separate variables for msvc/kern32 have been removed and all win32 libc directory paths have been combined into a ZigList since we're querying more than two directories and differentiating one from another doesn't matter to lld.

analyze.cpp:

The existing functions were extended to support querying libc libs & libc headers at runtime.

codegen.cpp/hpp:

Microsoft uses the new 'Universal C Runtime' name now. Doesn't matter from a functionality standpoint. I left the compiler switches as is to not introduce any breaking changes.

link.cpp:

We're linking 4 libs and generating another in order to support the UCRT.
Dynamic: msvcrt/d, vcruntime/d, ucrt/d, legacy_stdio_definitions.lib
Static: libcmt/d, libvcruntime/d libucrt/d, legacy_stdio_definitions.lib

main.cpp:

Update function call names.

os.cpp/hpp:

COM/Registry interface for querying Windows UCRT/SDK.

f1072d0d9f use llvm named structs for const values when possible 
normally we want to use llvm types for constants. but
union constants (which are found inside enums) when
they are initialized with the non-most-aligned-member
must be unnamed structs.

these bubble up to all aggregate types. if a constant of
an aggregate type contains, recursively, a union constant
with a non-most-aligned-member initialized, the aggregate
typed constant must be unnamed too.

this fixes some of the asserts that were coming in from
llvm master branch.

1828f8eb8e fix missing compiler_rt in release modes 
the optimizer was deleting compiler_rt symbols, so I changed

also changed LinkOnce to mean linkonce_odr in llvm and
Weak to mean weak_odr in llvm.

d7e28f991d remove CXX ABI workaround 
the actual solution is you must compile zig with the same

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.

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

91536813ec macos updates 
* try some macos travis stuff
 * put c in the link libs for macos since we always link with libSystem
 * for non-native targets on macos, allow runtime symbol resolution
   - it's causing an infinite loop in LLD.
 * for macos, always build compiler_rt and turn on LinkOnce because
   compiler_rt on darwin is missing some stuff.
