Should IFN_MASK_LOAD/STORE really go through this? I thought those have
first argument address of the memory being conditionally loaded/stored, not
function address.
No it shouldn't, my bad...
Surprising testing didn't catch it though, I'm guessing
gimple_call_addr_fndecl just returned null everytime for those. I'll
clean it up.
