Paulo Matos d3a0a65bf0 Reland: "[WebAssembly] Add new pass to lower int/ptr conversions of reftypes" 
Add new pass LowerRefTypesIntPtrConv to generate debugtrap
instruction for an inttoptr and ptrtoint of a reference type instead
of erroring, since calling these instructions on non-integral pointers
has been since allowed (see ac81cb7e6).

Paulo Matos 46667a1003 [WebAssembly] Implementation of global.get/set for reftypes in LLVM IR 
Reland of 31859f896.

This change implements new DAG notes GLOBAL_GET/GLOBAL_SET, and
lowering methods for load and stores of reference types from IR
globals. Once the lowering creates the new nodes, tablegen pattern
matches those and converts them to Wasm global.get/set.
