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

closes #618

Josh Wolfe
a44283b0b2 rework std.base64 api 
* rename decode to decodeExactUnsafe.
* add decodeExact, which checks for invalid chars and padding.
* add decodeWithIgnore, which also allows ignoring chars.
* alphabets are supplied to the decoders with their
  char-to-index mapping already built, which enables it to be
  done at comptime.
* all decode/encode apis except decodeWithIgnore require dest
  to be the exactly correct length. This is calculated by a
  calc function corresponding to each api. These apis no longer
  return the dest parameter.
* for decodeWithIgnore, an exact size cannot be known a priori.
  Instead, a calc function gives an upperbound, and a runtime
  error is returned in case of overflow. decodeWithIgnore
  returns the number of bytes written to dest.

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.

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.

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.

This covers the majority of the functions as covered by the C99

Code is adapted primarily from musl libc, with the pow and standard

Changes:

 - Remove assert expose in index and import as needed.
 - Add float log function and merge with existing base 2 integer
   implementation.

the plan is to use AT&T for now since it at least works,
and eventually zig will have its own assembly parser for
x86 and it will be as close to NASM as possible.

This changes the error message "return value ignored" to "expression value is ignored".
This is because this error also applies to {1;}, which has no function calls.

Also fix ignored expression values in std and test.
