Add .type, .hidden, and .size to the new fiat ADX assembly
.type seems to be needed for the unwind tester to report symbols
correctly. I assume it does other useful things. .hidden
(.private_extern on macOS) keeps it from being exported out of shared
libraries. I'm not positive what .size does, but if ELF wants to know
the size of the function, we should probably tell it that.
