On 64-bit we can do comparisons of 32-bit values by extending those
values to 64-bit, subtracting them, and then getting the high bit of
the result. For registers this is always cheaper than using the carry
bit sequence; and if the comparison involves a constant, this is cheaper
than the sequence we previously generated in half of the cases (and the
same cost in the other cases).
After this, the only sequence left that is using the mfcr insn is the
one doing signed comparison of Pmode registers.

The problem in the PR is that some i386 optabs FAIL when
optimising for size rather than speed. The gimple level generally
needs access to this information before calling the generator,
so this patch adds a new hook to say whether an optab should
be used when optimising for size or speed. It also has a "both"
option for cases where we want code that is optimised for both
size and speed.
I've passed the optab to the target hook because I think in most
cases that's more useful than the instruction code. We could pass
both if there's a use for it though.
At the moment the match-and-simplify code doesn't have direct access
to the target block, so for now I've used "both" there.
Tested on x86_64-linux-gnu and powerpc64-linux-gnu.

This patch makes it a compile-time error for an internal-fn optab
to FAIL. There are certainly other optabs and patterns besides these
that aren't allowed to fail, but this at least deals with the immediate
point of controversy.
Tested normally on x86_64-linux-gnu. Also tested by building one
configuration per cpu directory. arc-elf and pdp11 didn't build
for unrelated reasons, but I checked that insn-emit.o built for
