eb6a8e6a3b fix f128 remainder division bug 
The modulo operation computed rem(b+rem(a,b), b) which produces -1
for a=1 and b=2.

Switch to a - b * trunc(a/b) which produces the expected result, 1.

Fix 1117: Use realpath in stage1 Darwin os_self_exe_path 
Issue: https://github.com/ziglang/zig/issues/1117

The macOS stage1 Zig compiler should look in Zig's real absolute path
for the Zig stdlib, but os_self_exe_path looks in its path as returned
by _NSGetExecutablePath, which may be a symlink.  This means that a
symlinked Zig cannot find the Zig stdlib.

This patch fixes the issue by resolving the _NSGetExecutablePath result
to the real path using realpath() before copying the result to the
output path.

d464b25322 support --target-arch wasm32 (#1094) 
Add wasm32 support to the build-obj, build-exe and build-lib commands
of the stage 1 compiler.  Wasm64 should work transparently once it's
supported in upstream LLVM.

To export a function:

    // lib.zig - for exposition, not necessary for this example
    pub use @import("add.zig");

    // add.zig
    export fn add(a: i32, b: i32) i32 {
        return a + b;
    }

To import a function:

    // cube.zig
    extern fn square(x: i32) i32;

    export fn cube(x: i32) i32 {
        return x * square(x);
    }
