6dba1f1c8e slice and array re-work plus some misc. changes
* `@truncate` builtin allows casting to the same size integer.
   It also performs two's complement casting between signed and
   unsigned integers.
 * The idiomatic way to convert between bytes and numbers is now
   `mem.readInt` and `mem.writeInt` instead of an unsafe cast.
   It works at compile time, is safer, and looks cleaner.
 * Implicitly casting an array to a slice is allowed only if the
   slice is const.
 * Constant pointer values know if their memory is from a compile-
   time constant value or a compile-time variable.
 * Cast from [N]u8 to []T no longer allowed, but [N]u8 to []const T
   still allowed.
 * Fix inability to pass a mutable pointer to comptime variable at
   compile-time to a function and have the function modify the
   memory pointed to by the pointer.
 * Add the `comptime T: type` parameter back to mem.eql. Prevents
   accidentally creating instantiations for arrays.

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

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.

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`

cf9b21c09f MacOSX compatibility
- Implemented some syscall for MacOSX
- tested on : El Capitan 10.11 x86_64
- make self hosted test run on macosx
- modified run_test so it does not fail when parseh throws
  warnings (most of them are related to buildin types from
  gcc that arent defined in header files and unions)
- making -mmacosx-version-min and -mios-version-min works like
  gcc (command line paramers have precedence over enviroment variables)

06f2f4d64b change unreachable{} to @unreachable()
instead of a container init expression, it's a builtin
function call.
