Subject: [WebAssembly] Update wasm builtin functions to match spec changes.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=f8c49657e44ac6b04664fca5e3192c2227ad537a;p=clang

[WebAssembly] Update wasm builtin functions to match spec changes.

The page_size operator has been removed from the spec, and the resize_memory
operator has been changed to grow_memory.
