Dan Gohman 9f8ee03772 [WebAssembly] Update to the new names for the memory builtin functions. 
The WebAssembly committee has decided on the names `memory.size` and
`memory.grow` for the memory intrinsics, so update the clang builtin
functions to follow those names, keeping both sets of old names in place
for compatibility.

Heejin Ahn b29a17ba21 [WebAssembly] Restore __builtin_wasm_rethrow builtin 
Summary:
Restore the `__builtin_wasm_rethrow` builtin deleted in D37931. On second
thought, it appears it can be used to implement `__cxa_rethrow`.

Heejin Ahn fa9e1fba8c Remove __builtin_wasm_rethrow builtin 
Summary:
Remove `__builtin_wasm_rethrow` builtin. I thought it was required to implement
`__cxa_rethrow` function in libcxxabi, but it turned out it will be using
`__builtin_wasm_throw` instead.
