601e831f1d Add builtin for llvm.wasm.memory.grow.i32 intrinsic 
This will allow the developer to request additional memory pages
from the runtime to be allocated for the Wasm app. Typical usage:

```zig
var wasm_pages = @wasmMemorySize();
@wasmMemoryGrow(1);
@import("std").debug.assert((wasm_pages + 1) == @wasmMemorySize());
```

ce3f0077cf Add builtin for llvm.wasm.memory.size.i32 instrinsic 
This will allow the developer to poll the runtime for currently
allocated memory in the number of Wasm pages. Typical usage:

```zig
var wasm_pages = @wasmMemorySize();
@import("std").debug.assert(wasm_pages > 0);
```

0ff5d7b24e Add option for overriding the stack size 
This commit adds a `--stack [size]` link-time option to zig compiler
allowing the user to override the default stack size set for the
specified executable/library format. This is currently limited to
ELF, COFF and Wasm however (i.e., Mach-O is excluded).

cde7c75676 Increase default Wasm stack to 1MB 
This commit increases the default Wasm stack to 1MB from the default
of 1 Wasm page which equal 64KB. This seems like a reasonable default
size while at the same time not overly large. Also, Rust lang seems
to be favouring this default as well: [rust-lang#50083].

015c899297 Make align expr on fns a compile error in Wasm 
In Wasm, specifying alignment of function pointers makes little sense
since function pointers are in fact indices to a Wasm table, therefore
any alignment check on those is invalid. This can cause unexpected
behaviour when checking expected alignment with `@ptrToInt(fn_ptr)`
or similar. This commit proposes to make `align` expressions a
compile error when compiled to Wasm architecture.
