29defd705d back to AT&T syntax for assembly 
this reverts 5c04730534.

sadly the quality of the intel dialect in llvm's assembly
parser has many frustrating bugs, and generally has unfortunate
syntax.

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.

c6605cba83 blocks check that their statements are void 
closes #291

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.
This caught a bug in debug.readAllocBytes where an early Eof error would have been missed.
See #219.

   `std.build.Builder` to describe the targets, and then the zig
   build system prints TODO: build these targets. See #204
 * add `@bitcast` which is mainly used for pointer reinterpret
   casting and make explicit casting not do pointer reinterpretation.

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

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.

one can use:

7ce7e2c9d1 emit error for extern function 
with byvalue return value or parameter.

currently we don't codegen byvalue parameters or return values
correctly for C compatibilty functions so instead of generating
incorrect code, we emit a compile error.

eventually we'll support this feature and remove the compile error.

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)

49a4b1b930 ability to cast explicitly from int to enum 
This commit also fixes a bug where pure functions are marked with
the read-only attribute in debug mode. This resulted in incorrect
codegen because calls to read-only functions with unused values
were not generated.

For example, a call to assert() would not be generated if assert
is marked with read-only. Which it *is* marked with in release
mode.
