Andrew Kelley fc100d7b3b lots of miscellaneous things all in one big commit
* add `@compileLog(...)` builtin function
   - Helps debug code running at compile time
   - See #240
 * fix crash when there is an error on the start value of a slice
 * add implicit cast from int and float types to int and float
   literals if the value is known at compile time
 * make array concatenation work with slices in addition to
   arrays and c string literals
 * fix compile error message for something not having field access
 * fix crash when `@setDebugSafety()` was called from a
   function being evaluated at compile-time
 * fix compile-time evaluation of overflow math builtins.
 * avoid debug safety panic handler in builtin.o and compiler_rt.o
   since we use no debug safety in these modules anyway
 * add compiler_rt functions for division on ARM
   - Closes #254
 * move default panic handler to std.debug so users can
   call it manually
 * std.io.printf supports a width in the format specifier

Andrew Kelley 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) ...
```

Andrew Kelley 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`
2017-01-24 02:02:48 -05:00

 * fix indent when rendering container decl AST
 * IR: prevent duplicate generation of code when it is partially
   compile-time evaluated
