29defd705d back to AT&T syntax for assembly
this reverts 5c04730534ea7933855429c5fc5dc7b22eba7bc2.

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.

7b0542d08b build system: consolidate duplicate code and more
* add ability to add assembly files when building an exe, obj, or lib
 * add implicit cast from `[N]T` to `?[]const T` (closes #343)
 * remove link_exe and link_lib in favor of allowing build_exe and
   build_lib support no root zig source file

afa80da857 revert the last 3 compile time improvements
they introduced complexity into the compiler and didn't
really help.

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.

7f47b0c271 run alwaysinline pass in debug mode
before this commit, the optimized IR code that is displayed in
--verbose mode is not actually what gets emitted to an object
file.

that is now corrected, and we make sure to run the alwaysinliner
pass even in debug mode, so you can rely on "inline" keyword
inlining a function, guaranteed.

 * `--name` parameter is optional when it can be inferred from the
   root source filename. closes #207
 * `zig build` now looks for `build.zig` which interacts with
   `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.
   Closes #290

 * remove `@setFnVisible` builtin and add @setGlobalLinkage builtin
   which is more powerful
 * add `@panic` builtin function.
 * fix collision of symbols with extern prototypes and internal
   function names
 * add stack protector safety when linking against libc. To add
   the safety mechanism without libc requires implementing
