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

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.

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.
