8a859afd58 std.io supports printing integers as hex values
remove "unnecessary if statement" error
this "depends on compile variable" code is too hard to validate,
and has false negatives. not worth it right now.

std.str removed, instead use std.mem.

std.mem.eql and std.mem.sliceEql merged and do not require explicit
type argument.

07a71fc322 improved behavior on debug safety crash
* instead of emitting a breakpoint for a debug safety crash,
   zig calls a panic function which prints an error message
   and a stack trace and then calls abort.
 * on freestanding OS, this panic function has a default
   implementation of a simple infinite loop.
 * users can override the panic implementation by providing
   `pub fn panic(message: []const u8) -> unreachable { }`
 * workaround for LLVM segfaulting when you try to use cold
   calling convention on ARM.

5a86c04996 add volatileStore() builtin function
See #238

We can revisit how volatile will work later - for now
here's a builtin function to do it.

b78c91951a remove ability to mark if and switch as inline
if and switch are implicitly inline if the condition/target
expression is known at compile time.

instead of:

```
inline if (condition) ...
inline switch (target) ...
```

one can use:

```
if (comptime condition) ...
switch (comptime target) ...
```

4b3f18de3c printf var args proof of concept
See #167

Need to troubleshoot when we send 2 slices to printf. It goes
into an infinite loop.

This commit introduces 4 builtin functions:

 * `@isInteger`
 * `@isFloat`
 * `@canImplictCast`
 * `@typeName`

 * fix var args when number of args passed is 0
 * implement const value equality for structs
 * fix indent when rendering container decl AST
 * IR: prevent duplicate generation of code when it is partially
   compile-time evaluated
 * implement compile time struct field pointer evaluation
 * fix compile time evaluation of slicing
