Subzero: Clean up the runtime implementation.
The runtime helpers are given more consistent names:
__Sz_<bitcode>_<type1>_<type2>
Missing helpers (various vector bitcasts) are implemented.
We'd prefer to avoid calling external library functions, e.g. in compiler-rt, but even llc uses these helpers for some bitcode on x86-32, so the alternative is to copy their implementation into Subzero's runtime.
