  RuntimeLibcalls: Remove table of soft float compare cond codes

Previously we had a table of entries for every Libcall for
the comparison to use against an integer 0 if it was a soft
float compare function. This was only relevant to a handful of
opcodes, so it was wasteful. Now that we can distinguish the
abstract libcall for the compare with the concrete implementation,
we can just directly hardcode the comparison against the libcall
impl without this configuration system.
