Before, if you did something like:
```
const hi1 = "hi";
const hi2 = hi1;
```
This would create the "hi" data twice in the built object.
But since the value is const we don't have to duplicate the
data, now we take advantage of this fact.

* skip installing std/rand_test.zig as it's not needed beyond running
the std lib tests
* add std.math.floor function
* add setFloatMode builtin function to choose between
builtin.FloatMode.Optimized (default) and builtin.FloatMode.Strict
(Optimized is equivalent to -ffast-math in gcc)
* add `@divTrunc` and `@divFloor` functions
* add `@rem` and `@mod` functions
* add compile error for `/` and `%` with signed integers
* add `.bit_count` for float primitive types

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.
* 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
they introduced complexity into the compiler and didn't
really help.

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.
See #329
Supporting work:
* move std.cstr.Buffer0 to std.buffer.Buffer
* add build.zig to example/shared_library/ and add an automated test
for it
* add std.list.List.resizeDown
* improve std.os.makePath
- no longer recursive
- takes into account . and ..
* add std.os.path.isAbsolute
* add std.os.path.resolve
* reimplement std.os.path.dirname
- no longer requires an allocator
- handles edge cases correctly
* zig build system: create standard dynamic library sym links
* unwrapping an error results in a panic message that contains
the error name
* rename error.SysResources to error.SystemResources
* add std.os.symLink
* add std.os.deleteFile
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.
See #306
where Int is an integer type
also introduce `@intToPtr` builtin for converting a usize
to a pointer. users now have to use this instead of `(&T)(int)`.
