## Message

````
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());
```
