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.

[VS 2015 Breaking Changes](https://msdn.microsoft.com/en-us/library/bb531344.aspx)
* add ability to add assembly files when building an exe, obj, or lib
* add implicit cast from `[N]T` to `?[]const T` (closes#343)
* remove link_exe and link_lib in favor of allowing build_exe and
build_lib support no root zig source file
See #329
Supporting work:
* move std.cstr.Buffer0 to std.buffer.Buffer
* add build.zig to example/shared_library/ and add an automated test
for it
* add std.list.List.resizeDown
* improve std.os.makePath
- no longer recursive
- takes into account . and ..
* add std.os.path.isAbsolute
* add std.os.path.resolve
* reimplement std.os.path.dirname
- no longer requires an allocator
- handles edge cases correctly
* zig build system: create standard dynamic library sym links
* unwrapping an error results in a panic message that contains
the error name
* rename error.SysResources to error.SystemResources
* add std.os.symLink
* add std.os.deleteFile
* Fix assertion failure when switching on type.
Closes#310
* Update zig build system to support user defined options.
See #204
* fmt.format supports {sNNN} to set padding for a buffer arg.
* add std.fmt.bufPrint and std.fmt.allocPrint
* std.hash_map.HashMap.put returns the previous value
* add std.mem.startsWith
* `zig build --export [obj|lib|exe]` changed to `zig build_obj`,
`zig build_lib` and `zig build_exe` respectively.
* `--name` parameter is optional when it can be inferred from the
root source filename. closes#207
* `zig build` now looks for `build.zig` which interacts with
`std.build.Builder` to describe the targets, and then the zig
build system prints TODO: build these targets. See #204
* add `@bitcast` which is mainly used for pointer reinterpret
casting and make explicit casting not do pointer reinterpretation.
Closes#290
* fix debug info for byval parameters
* sort command line help options
* `std.debug.panic` supports format string printing
* add `std.mem.IncrementingAllocator`
* fix const ptr to a variable with data changing at runtime.
closes#289
