  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.

  ARM: Unconditionally set eabi libcall calling convs in RuntimeLibcalls

This fully consolidates all the calling convention configuration into
RuntimeLibcallInfo. I'm assuming that __aeabi functions have a universal
calling convention, and on other ABIs just don't use them. This will
enable splitting of RuntimeLibcallInfo into the ABI and lowering component.

  ARM: Start moving runtime libcalls into tablegen

We still need to manually set the calling conventions of
some libcalls until the lowering is separated out.
