c9858f833c stage2: fix building stage3 in release mode 
Previously, comptime function calls could cause a crash in the hash
function due to a lazy value depending on an unresolved type.

922d8378e7 stage2: Add limited WASI support for selfExePath and globalCacheDir 
This change adds support for locating the Zig executable and the library
and global cache directories, based on looking in the fixed "/zig" and
"/cache" directories.

Since our argv[0] on WASI is just the basename (any absolute/relative
path information is deleted by the runtime), there's very limited
introspection we can do on WASI, so we rely on these fixed directories.
These can be provided on the command-line using `--mapdir`, as follows:

```
wasmtime --mapdir=/cwd::. --mapdir=/cache::"$HOME/.cache/zig" --mapdir=/zig::./zig-out/ ./zig-out/bin/zig.wasm
```

7b090df668 stdlib std.os: Improve wasi-libc parity for WASI CWD emulation 
Two major changes here:
  1. We store the CWD as a simple `[]const u8` and lookup Preopens for
     every absolute or CWD-referenced file operation, based on the
     Preopen with the longest match (i.e. most specific path)
  2. Preorders are normalized to POSIX absolute paths at init time.
     Behavior depends on the "cwd_root" parameter of `initPreopensWasi`:

	`cwd_root` is used for any Preopens that start with "."

	  For example:
            "./foo/bar" - inits to -> "{cwd_root}/foo/bar"
            "foo/bar"   - inits to -> "/foo/bar"
	    "/foo/bar"  - inits to -> "/foo/bar"

        `cwd_root` must be an absolute path.

	Using "/" as `cwd_root` gives behavior similar to wasi-libc.

897df18573 stage2: fix @mulAdd on aarch64 Darwin 
According to Apple docs, the long double type is a double precision
IEEE754 binary floating-point type, which makes it identical to the
double type. This behavior contrasts to the standard specification,
in which a long double is a quad-precision, IEEE754 binary,
floating-point type.

Thus, we need to take this into account when using the compiler
intrinsics so that we select the correct function version for
FloatMulAdd.
