VECREDUCE_FMIN/FMAX wil be lowered to fminnmv/fmaxnmv. They needn't be custom
lowered through an intrinsic to do it, and can be treated as Legal instead.

Add extra test coverage with cases that showed mis-compiles in earlier
versions of an upcoming patch. Also add tests for integer phis

This reverts commit c0f9d7b0.

A build error has been reported with gcc-7.

This patch fixes:

https://github.com/llvm/llvm-project/issues/63240

Something like:
    `%r = mul %x, <33, 33, 33, ...>`

Is best lowered as:
    `%tmp = %shl x, <5, 5, 5>; %r = add %tmp, %x`

As well, since vectors have non-destructive shifts, we can also do
cases where the multiply constant is `Pow2A +/- Pow2B` for arbitrary A
and B, unlike in the scalar case where the extra `mov` instructions
make it not worth it.

We canonicalize rotate-right -> rotate-left in other places. Makes
sense to do so here as well.

Only do so if we don't create more instructions, so either both
rotates have one use or one of the rotates has one use and both `AX`
and `AY` are constant.

This patch aims to clarify which part of the docs is the summary and which
part is the description.

I did a preview of the output and think the suggested bold and italic style
is much clearer and looks reasonably nice.

I've considered also to enforce capitalization of the first letter of the
summary and ending with a dot (as discussed in
https://reviews.llvm.org/D151649), but it seems to me that the tradeoff in
extra test running time is not worth it. Currently, `emitOpDoc` is not
triggered for every `summary` during `check-mlir`.

This is a quick fix for an assert when the source and dest have
different address spaces. The pointer compare needs to have matching
types, but we can't generically introduce addrspacecast and we don't
know if the address spaces alias.

Since ROLBRd needs an implicit R1 (on AVR) or an implicit R17 (on AVRTiny),
we split ROLBRd to ROLBRdR1 (on AVR) and ROLBRdR17 (on AVRTiny).
