[PowerPC] Don't crash on PPC32 i64 fp_to_uint on modern cores

When we have an instruction for this (and, thus, don't generate a runtime
call), we need to custom type legalize this (in a trivial way, just as we do
for fp_to_sint).

Fixes PR23173.

For the most common ones (such as fadd), we already did the promotion.
Do the same thing for all the others.

Currently, we'll just crash/assert on all these operations, as
there's no hardware or libcall support whatsoever.

f16 (half) is specified as an interchange - not arithmetic - format,
and is expected to be promoted to single-precision for arithmetic
operations.

While there, teach the legalizer about promoting some of the (mostly
floating-point) operations that we never needed before.

AArch64: Don't lower ISD::SELECT to ISD::SELECT_CC

Instead of lowering SELECT to SELECT_CC which is further lowered later
immediately call the SELECT_CC lowering code. This is preferable
because:
- Avoids an unnecessary roundtrip through the legalization queues with
  an intermediate node.
- More importantly: Lowered operations get visited last leading to SELECT_CC
  getting visited with legalized operands and unlegalized ones for preexisting
  SELECT_CC nodes. This does not hurt the current code (hence no testcase) but
  is required for another patch I am working on.
